Question

Ravi goes once round a circular track of diameter 135 meters in 5 minutes. Find his speed.

Answer 1

Answer:

1.41 m/s

Explanation:

diameter- 135 meters

radius-135/2 m

time-5 min =300 sec

circumference= 2πr

                        = 2×22/7×135/2

                        =5940/14

                        =2970/7 m

speed- 2970/7 ÷300

         =1.41 m/s
