Question

A biker covers 60 km in 70 minutes on a straight road . Calculate its speed and velocity .

Answer 1

Hola

So the distance = 60km

Time taken = 70 minutes

speed = distance / time

Therefore speed = 60/70 * 60 ( To convert it into hour)

= 3600/70 km/hr

360/7 = 51.4 km /hr approximately.

So if u want u can keep it as it is, 360/7 km /hr.

Velocity also same because it's straight line motion.

Glad to help you

Answer 2

distance = 60km = 60000 meter
time = 70 x 60 = 4200 s

speed = distance/time

= 60000/4200

600/42

= 14.28 m/s

or in km/hr it
we need to multiply it by 18/5

14.28 x 18/5

25.704/5

speed = 51.408 km/hr
----------------------------------------------
here velocity will remain the same as the bike is travelling in same straight line and there is not change in its direction
