Question

A rectangular field is 90 m by 70 m. A man walks around it at the rate of 4 km
per hour. What time will he take in making 5 rounds?​

Answer 1

Answer:

He will take 24 minutes in making 5 rounds.

Step-by-step explanation:

Perimeter the rectangular field = 2(L+B)

= 2(90+70)

= 2×160

= 320 m

Given, No of rounds made = 5

Hence, total distance = 320 × 5

= 1600 m = 1.6 km

Given, Speed = 4 km/hr

Hence, Time = Distance / Speed

= 1.6 / 4 = 16/40 = 0.4 hr

= 0.4 × 60 = 24 mins. (ans).
