Given
Length =25m
Breath =15m
Speed =7.2km/h
The boy running around the field so we need to calculate Perimeter of field
Perimeter of rectangle =2(l+b)
=2(25+15)
=2x40
=80m
Changing speed in m/s (multiple 7.2km/hr with 5/18)
Speed=7.2x5/18
=2m/s
Time taken by boy=80/2 =40 seconds
This is ur ans hope it will help you
