Solutions

Question 1
The movie yesterday was 2 hours and 15 minutes long.

Question 2
To find the time when the steak was fully cooked, we need to add the cooking time (15 minutes) to the starting time (9:45). This gives us a total time of 10:00. Therefore, the steak was fully cooked by 10:00.

Question 3
Step 1: Add the number of minutes Tom went to bed later to the usual bedtime. 10:00 pm + 25 minutes = 10:25 pm Step 2: Convert the time from 24-hour format to 12-hour format, if desired. 10:25 pm can also be expressed as 10:25 at night.

Question 4
Chris had to wait for 25 minutes for his appointment as the difference between his arrival time and the appointment time is 25 minutes.

Question 5
Subtract the time the patty was taken out of the fridge from the time it was started to be grilled. 12:30 - 11:15 = 1 hour and 15 minutes. So the patty was out of the fridge for 1 hour and 15 minutes.

Question 6
Mr. Lee started to fry the fish at 4:00 and the marination time was 120 minutes. Therefore, he started marinating the fish 2 hours before 4:00, which is at 2:00.

Question 7
To find out how many minutes Mark slept for, we can multiply the number of hours he slept by the number of minutes in an hour. So, 8 hours x 60 minutes = 480 minutes. Therefore, Mark slept for 480 minutes.

Question 8
To find out how many minutes of sleep Samuel had, we need to multiply the number of hours he slept by the number of minutes in an hour. So, 9 hours x 60 minutes per hour = 540 minutes of sleep.

Question 9
To find out how many minutes Sue slept for, we can multiply the number of hours she slept by the number of minutes in an hour. So, 8 hours x 60 minutes = 480 minutes. Therefore, Sue slept for 480 minutes.

Question 10
Karen's usual bus time is 9:15 am. We can subtract 30 minutes from her taking the bus at quarter to nine, which is 8:45 am. Therefore, her usual bus time is 9:15 am.

Question 11
Sarah had 30 minutes to board the flight as the difference between her arrival time and the departure time is 30 minutes.

Question 12
Chris had to wait for 25 minutes for his appointment as the difference between his arrival time and the appointment time is 25 minutes.

Question 13
To find the time it takes for Shane to bake 4 cakes, we need to use proportion. If 1 cake takes 30 minutes to bake, then 4 cakes will take 4 times as long, which is 120 minutes or 2 hours. Therefore, it will take Shane 2 hours to bake 4 cakes.

Question 14
Tom's usual time is 7:50 am. We can add 20 minutes to half past seven, which is 7:50 am. Therefore, his usual time is 7:50 am.

Question 15
The patient had to rest for 240 minutes (4 hours x 60 minutes per hour).

Question 16
To calculate the minutes Mark had to board the train, we need to subtract the time he arrived at the train station from the departure time. 8:15 minus 7:55 is equal to 20 minutes. Therefore, Mark had 20 minutes to board the train.

Question 17
The first appointment on most Wednesdays is at 8:10 AM.

Question 18
To find the total time Amy took to prepare all the games, we need to multiply the time taken to prepare one game with the total number of games. So, 2 minutes per game x 3 games = 6 minutes. Therefore, it took Amy 6 minutes to prepare all the games.

Question 19
To solve this problem, we need to add 25 minutes to the time the musicians arrived at the concert hall. One minute past seven is 7:01 pm. Adding 25 more minutes to it gives us 7:26 pm. Therefore, the musicians started rehearsing at 7:26 pm.

Question 20
The patient had to rest for 600 minutes (10 hours x 60 minutes per hour).
