Question

John ran 4 laps of the track in 5 minutes, 40 seconds

Answer 1

Well, lets think about this. We need to ask our self how many seconds are in one minute. There are 60 seconds in 1 minute. We know he did 4 laps in 5 minutes and 40 seconds. You can change the minutes to seconds by multiplying 60 * 5 = 300 seconds. So 5 minutes = 300 seconds. Now just take the 40 seconds and add it to the 300 seconds, which will give you 340 seconds. So John ran 4 laps in 340 seconds. B wants to know how many seconds it took John per lap...We can find this by dividing 340 by 4 340/4 = 85.

A) 340 seconds

B) 85 sec/lap

Answer 2

A)
$(5 \times 60) + 40 = 340s$
b)
$340 \div 4 = 85s$
