Explanation:

a cyclist moving on a circular track of radius 50 M completes one revolution in 4 minutes what is (a) average speed (B) average velocity in one full revolution

Answer 2

Given - Radius =50m
           Diameter =100m (distance)
          t = 4 min = 4 x 60 = 240 s
 
(i) Avg. speed - total Distance/ Total time

                      total distance = 2$\pi$r  (circumference)
                              2x22/7x50 = 2200/7 m

                 total time = 4 min = 4 x 60 = 240 s  

.: avg speed = total distance/total time

                          (2200/7)/(240)

=
                 55/42
