Solutions

Question 1
John arrived at the library earlier. To figure this out, we can add the time John started walking (7:15 a.m.) to the amount of time he walked (45 minutes) to get the time he arrived at the library (8:00 a.m.). Similarly, we can add the time Mark started walking (7:45 a.m.) to the amount of time he walked (25 minutes) to get the time he arrived at the library (8:10 a.m.). Therefore, John arrived at the library earlier than Mark.

Question 2
To find the time the band finished signing autographs, we need to add 45 minutes to the time when the concert ended. Therefore, the band finished signing autographs at 10:45 p.m.

Question 3
The doctor started her lunch break 25 minutes late at 12:55 p.m. Her lunch break lasts for 1 hour, so adding 1 hour to 12:55 p.m. gives us 1:55 p.m. Therefore, she finished her lunch break at 1:55 p.m.

Question 4
Adding 15 minutes to 7:30 p.m. gives us 7:45 p.m. Therefore, Jenna arrived at the party at 7:45 p.m.

Question 5
To calculate the waiting time, we need to subtract the current time (10:20 a.m.) from the opening time (11:00 a.m.). 11:00 a.m. - 10:20 a.m. = 40 minutes So the waiting time until the park opens is 40 minutes.

Question 6
Since the office closed at 6:00 p.m., the supervisor left at 6:10 p.m. (10 minutes after closing). The IT person left 20 minutes after the supervisor left, so the IT person left at 6:30 p.m.

Question 7
Mark's family spent a total of 40 minutes + 1 hour and 15 minutes = 1 hour and 55 minutes at the museum. So, they left the museum at 3:15 p.m., 1 hour and 55 minutes after arriving at 1:20 p.m.

Question 8
To calculate the waiting time, we need to subtract the door opening time (6:30 p.m.) from the concert start time (7:00 p.m.). 7:00 p.m. - 6:30 p.m. = 30 minutes So the waiting time for the concert is 30 minutes.

Question 9
The sum of 24 and 38 equals 62.

Question 10
John has 8 apples. Initially, he had 3 apples, and Jane gave him 5 more apples, which adds up to 8.

Question 11
The Johnson family spent a total of 1 hour and 15 minutes + 3 hours and 30 minutes = 4 hours and 45 minutes at the zoo. So, they left the zoo at 2:30 p.m., 4 hours and 45 minutes after arriving at 9:45 a.m.

Question 12
To find the arrival time of the train, we need to add the travel time to the delayed departure time. First, we convert the travel time of 4 hours and 30 minutes to just minutes, which is 270. Then we add the delayed departure time of 15 minutes to get a total delay of 285 minutes. Adding this delay to the scheduled departure time of 3:00 p.m., we get an arrival time of 7:45 p.m. Therefore, the answer is 7:45 p.m.

Question 13
The solution to this question cannot be determined without knowing the time when the school ends.

Question 14
To find the time traveled by the bicycle, we subtract the departure time from the arrival time: 1:30 - 11:00 = 2:30 or 2 hours and 30 minutes.

Question 15
You still need 2 cups of flour as you have already used 2 cups out of the total 4 cups.

Question 16
The solution to this question cannot be determined without knowing the time when the school ends.

Question 17
To find the time traveled by the bus, we subtract the departure time from the arrival time: 10:30 - 6:45 = 3:45 or 3 hours and 45 minutes.

Question 18
To solve this problem, we need to add up the time it took Mike to get to school, pick up his textbooks, and wait before class. 7:45 a.m. to 8:05 a.m. is 20 minutes, and waiting for 15 more minutes brings the total time to 35 minutes. Therefore, it was 35 minutes from the time he left his house until the class began.

Question 19
The solution to this question cannot be determined without knowing the time when the school ends.

Question 20
To find the arrival time of the boat, we need to add the travel time to the delayed departure time. First, we convert the travel time of 3 hours and 45 minutes to just minutes, which is 225. Then we add the delayed departure time of 20 minutes to get a total delay of 245 minutes. Adding this delay to the scheduled departure time of 7:00 a.m., we get an arrival time of 11:05 a.m. Therefore, the answer is 11:05 a.m.
