Question

Greg sets his watch for the correct time on Wednesday. exactly one week later, he finds that his watch has lost 3 1/4 minutes. what is the overall change in the time after 8 weeks.

Answer 1

☆Convert minutes to seconds

3 1/4 minutes

= 3 min = 180 sec
= 1/4 min = (1/4 × 60)=(60/4) = 15 sec

Total time= 180 + 15 = 195 sec / week

☆Multiply the time taken by how many weeks

8 × 195 sec = 1560 sec

1560 sec ÷ 60 = 26 minutes

The overall change in time after 8 weeks is 26 minutes

Answer 2

To find this, use the expression 3 1/4 • x
X represents the amount of weeks
In this case, it is asking for 8 weeks, so replace x with 8.
3 1/4 x 8
3 times 8 is 24, 1/4 times 8 is 2. Add these together.
The answer is 26.
