Question

A car traveks at a speed of 50 metre/secs. Find its speed in km/hr
be​

Answer 1

${Solution}$

Given :-

• Speed of car is 50m/s

To find :-

• We have to find its speed in km/hr

Solution :-

For converting speed m/s - km/hr We have to multiply with 18/5

1m/s = 18/5 km/hr

So, 50 m/s = 50× 18/5

50m/s = 10 × 18 km/hr

50m/s = 180km/hr

For converting km/hr - m/s we have to multiply by 5/18

For converting m/s -km/hr we have to multiply by 18/5

Speed = Distance / Time

Distance = Speed × time

Time = Distance /speed

Velocity = Displacement /time

Time = Displacement/velocity

Displacement = Velocity × Time
