Question

A rectangular field is 72 m by 58 m. Amar walks round it at the rate of 3 km per hour. What time will he take in taking 2 rounds.​

Answer 1

Answer:

he will take 616.5 secs (approx)

Step-by-step explanation:

walking around =

perimeter

=2(72+58)

=2(130)

=260m

no 3km/h=0.83m/s

so time = distance/speed

time taken to cover 1 round

= 260/0.83

=313.25 (approx)

so time taken to cover 2 rounds

=313.25 × 2

=616.5 sec (approx)
