Question

Jeff walks 4 km each hour. How long will it take him to walk around a rectangular field 300m by 200m?

Answer 1

Answer:

15 minutes

Step-by-step explanation:

Length of rectangle = 300m

Breadth of rectangle = 200m

Perimeter = 2(l+b) = 2(300+200) m = 2(500) m = 1000m = 1 km

Distance covered in 1 hour = 4 km

Hence, time taken to cover 1 km = 1/4 hours = 15 minutes

Answer 2

15 minutes is the right answer
