Question

A tortoise is in the dessert. It walks at a speed of 7 meters per minute for 11.2 meters. For how many minutes does it walk?

Answer 1

time = distance/speed

time = 11.2/7 = 1.6 min

Answer 2

We know, speed = distance / time
Here, speed = 7 m/min
distance = 11.2 m

Substitute their values, 
7 = 11.2 / t
t = 11.2 / 7
t =1.6 min

In short, Your Answer would be 1.6 minutes

Hope this helps!
