Answer 2

Given:-

• Distance = 150m
• Time = 10seconds

To find :-

• Speed of the train

SOLUTION :-

For finding the speed we have formula

${Speed} = \dfrac{Total \:Distance}{Total\:Time}$

Plugging values:-

${Speed} = \dfrac{150m}{10s}$

${Speed} = 15m/s$

So, the speed of a train is 15m/s

know more :-

Distance = Speed×time

Time = Distance/Speed

Velocity = Displacement/Time

Time = Displacement ×Time

Displacement = Velocity ×time

• 1m/s = 18/5 km/hr
• 1km/hr = 5/18 m/s
