Question

A boy running along the boundary of a football field
of length 120m and breadth 80m at
a speed of
8 m/ sec. Find the time taken by the boy to complete
a round of the field.​

Answer 1

Answer:

50 seconds

Step-by-step explanation:

the perimeter of the field is 2(120+80) which is 400m

if he runs at 8m/second, then he will run 400 metres in 400/8=50 seconds

so it would take 50 seconds for the boy to complete a round of the field

hope this helped :)

Answer 2

Answer:

50 sec.

Step-by-step explanation:

round of a field = perimeter

perimeter = 2(l+b) = 2(120+80)= 400m

therefore time = d\s = 400/8 = 50 sec
