Question

Carl runs around a track 1.17 min how long would it take him to run 1.5 laps at his rate?

( round to 2 places)

Answer 1

It will take Carl 1.76 minutes to run 1.5 laps

Step-by-step explanation

We know from our problem that Chris runs a lap in 1.17 minutes, so he will run half a lap in half the time:
`(1.17)/(2) =0.585` minutes.

We have the time it takes Chris to run 1 lap and the time it takes him to run half (0.5) laps, so, to find how long it takes him to run 1.5 laps, we just need to add the two times:

Total time = 1.17 minutes + 0.585 minutes

Total time= 1.755

Since we need to round to two places, we check if the number after the 2nd place is 5 or bigger; if it is, we add 1 to the number on the 2nd place. The number after the 2nd place is 5, so we add 1 to the 5 in the 2nd place to get:

Total time = 1.76 minutes

Carl will run 1.5 laps in 1.76 minutes
