Question

find the average speed of a cycle of its initial speed is 10km/h and final speed is 30 km/h also find the distance covered if the cycle runs for half an hour​

Answer 1

initial speed, u = 10 km/h

final speed, v = 30 km/h

Average Velocity, Vav = ( u + v ) / 2

Vav = ( 10 + 30 ) / 2

Vav = 40/2

Vav = 20 Km/h

Distance covered, D = Vav × time

D = 20 × 1/2

D = 10 Km
