Question

1 A Bicyclist Travels With An Average Velocity Of 15 Km/hr North,for 20 Minutes.What Is The Displacement In K.M?

Answer 1

velocity = 15km/hr

time = 20min (0.3hr approx)

now, velocity = displacement / time

15 = d / 0.3

15x0.3 = d

d = 4.5km

displacement from start is 4.5km towards north

Answer 2

Answer:4.5 km/hr

Explanation:V=d/t

                     D=v*t

                     D=15 km/hr*0.3 hr (approximately)

                     D=4.5 km/hr
