Question

a motor car takes 50seconds to travel 500 metres what its speed in km/hr

Answer 1

Time = 50 seconds
Distance=500 m
Speed = Distance/Time
= 500/50
=10m/s
Speed in km/hr = 10 ×18/5
=36km/hr

Answer 2

Answer:

Speed of the motor car, v = 36 km/h

Explanation:

It is given that,

Distance travelled by the motor car, d = 500 meters

Time taken by the motorcar, t = 50 seconds

Let v is the speed of the motorcar. It can be calculated as :

$v=\dfrac{d}{t}$

$v=\dfrac{500\ m}{50\ s}$

v = 10 m/s

Since, 1 km = 1000 m

and 1 hour = 3600 s

So, v = 36 km/h

So, the speed of the motor car is 36 km/h. Hence, this is the required solution.
