Solutions

Question 1
John arrived at work earlier since he left 5 minutes earlier and his travel time is shorter than Emily's travel time.

Question 2
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 3
To find out what time the movie started, we need to subtract the length of the movie from the time they left the theater. We know they left the theater at 9:30pm and the movie was 2 hours and 15 minutes long. We subtract 2 hours and 15 minutes from 9:30pm and get 7:15pm as the start time of the movie. Therefore, the movie started at 7:15pm.

Question 4
The solution provided in the answer is correct. Since the opening time of the stores in the mall is not provided, it is impossible to determine how much time Tom needs to wait before the stores open. Therefore, the answer is as given in the question.

Question 5
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 6
To solve this problem, we need to subtract the length of the movie from the time they left the theater. 3:45 p.m. - 1 hour and 30 minutes = 2:15 p.m. Therefore, the movie started at 2:15 p.m.

Question 7
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 8
The sum of 24 and 38 equals 62.

Question 9
Since Sarah left home 15 minutes earlier than David, she arrived at school earlier, as she takes only 20 minutes to go to school while David takes 35 minutes. Therefore, the answer is Sarah.

Question 10
To find out the delay time, we can add 1 hour and 10 minutes to the scheduled departure time of 9:45 a.m. 1 hour and 10 minutes is 70 minutes in total. So, 9:45 a.m. + 70 minutes = 10:55 a.m. Therefore, the flight will depart at 10:55 a.m.

Question 11
If John arrives exactly at 3:30 p.m., then he does not need to wait. So the waiting time is 0 minutes.

Question 12
John has 8 apples. Initially, he had 3 apples, and Jane gave him 5 more apples, which adds up to 8.

Question 13
Add 45 minutes to 6:00 a.m. 6:00 a.m. + 45 minutes = 6:45 a.m.

Question 14
To determine the latest time for pick up, we need to know when the school ends. Without that information, we cannot calculate the latest pick-up time. Therefore, the answer given is correct.

Question 15
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.

Question 16
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 17
The solution provided in the answer is correct. Since the opening time of the stores in the mall is not provided, it is impossible to determine how much time Tom needs to wait before the stores open. Therefore, the answer is as given in the question.

Question 18
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 19
You still need 2 cups of flour as you have already used 2 cups out of the total 4 cups.

Question 20
To find the waiting time, subtract the arrival time from the opening time. 10:00 a.m. - 9:15 a.m. = 45 minutes.
