Answer 2

Answer:

10.56 minutes

Step-by-step explanation:

radius of a circle =35m

circumference of the circle is 2πr.

here r=35m

so circumference is 2×π×35=220m.

total path the boy has to follow=220×4=880m.

his walking speed=5km per hour= 5000m per 60 minutes

so he need 880÷(5000/60)=10.56 minutes to complete the path.
