Question 1.
Mr. Wagner lifts weights for 10 minutes and runs for 35 minutes. He finishes exercising at 6:15. When did he start exercising?
Answer:
Given,
Mr. Wagner lifts weights for 10 minutes and runs for 35 minutes.
10 + 35 = 45 minutes
He finishes exercising at 6:15.
6:15 can be written as 5 hours 75 minutes
Now subtract 45 minutes from the ending time to find the starting time of the exercise.
5 hour 75 minutes
-0 hour 45 minute
5 hour 30 minutes
Thus he starts exercising at 5:30

Question 2.
The train leaves at 7:15. Abby needs 15 minutes to get to the station, 20 minutes to pack, and 10 minutes to get ready. When should she start getting ready?
Answer:
Given,
The train leaves at 7:15.
Abby needs 15 minutes to get to the station, 20 minutes to pack, and 10 minutes to get ready.
15 + 20 + 10 = 45 minutes
Now subtract 45 minutes from the train leaving time to find when should she start getting ready.
7:15 – 45 minutes
7:15 = 6 hour 75 minutes
6 hour 75 minutes
-0 hour 45 minute
6 hours 30 minutes
Thus we should start getting ready by 6:30.

Solve

Use the picture graph to answer the questions.

Question 1.
Who practices 14 hours each month?
Answer:
Each single ball = 4 hours
Half ball = 2 hours
From the above picture graph, we can observe that Ines practices 14 hours each month as there are 3 full balls and 1 half ball.
3 × 4 = 12 hours
1/2 × 4 = 2 hours
12 + 2 – 14

Question 2.
How many fewer hours each month does Logan practice than lines?
Answer:
Ines practiced for 14 hours
Logan practices for 10 hours as there are 2 full balls and 1 half ball.
2 × 4 = 8
1/2 × 4 = 2
8 + 2 = 10 hours
We need to find how many fewer hours each month Logan practices than lines.
14 – 10 = 4 hours
Therefore Logan practices 4 fewer hours than Ines.

Question 3.
Who practices more than 8 hours but less than 12 hours?
Answer:
Logan practices for 10 hours as there are 2 full balls and 1 half ball.
2 × 4 = 8
1/2 × 4 = 2
8 + 2 = 10 hours
Thus Logan practices for more than 8 hours but less than 12 hours.
