Question

A tortoise is walking in the desert. It walks for

87.5
meters at a speed of
7
meters per minute. For how many minutes does it walk?

Answer 1

Time=Distance/Speed.
Time=87.5/7=25/2
Time=25/2*1/10=1.25mins or 1 minute and 25 seconds.

Answer 2

"Speed=distance divided by time =d/t 3m/min=37.5m/t t=(37.5m)/(3m/min) the meters goes away and you left with t in min t=12.5 min"
