a person walks at the rate of 4 km/hr. How long will he take to go round a square park, whose area is 2500m^2?​

Answer»

of SQUARE = 2500m^2

side of square = SQ RT 2500 = 50m

distance travelled in 1 round = 50(4) =200 m

distance travelled in 5 rounds = 200(5) =1000m = 1 km

SPEED =4 km/hr

time taken = distance /speed

= 1/4 hr

= 15 mins.
