Jill swam 200 meters in 2 minutes 42 seconds. If each lap is 50 meters long, which time is her estimated time, in seconds, per lap?

The time for each lap is 40.5 sec.

Step-by-step explanation:

Given,

He completed 200 m in 2 min 42 sec.

Each lap = 50 m

2 min 42 sec = 162 sec

To find the time for each lap.

Method

We will apply unitary method.

50 m = 1 lap

1 m = lap

200 m = ×200 laps

= 4 laps

Now,

He completed 4 laps in 162 sec

So, for 1 lap he took sec = 40.5 sec

Hence,

The time for each lap is 40.5 sec.
