Question

A bus takes 3 hours to cover a distance of 120 km calculate the speed in minute second

Answer 1

Time=3Hrs
Distance=120 Km
Speed=120/3=40km/hrs

Hence
40km/hrs are change in minute/second
=11.1111 Meter/sec

Answer 2

Given:

A bus takes 3 hours to cover 120 km.

To Find:

Speed of bus in meter per second?

Explanation:

• Speed can be defined as the rate at which someone or something moves or operates or is able to move or operate:
• In this given problem a bus covers the distance of 120 km in three hours.
• We know that speed is equal to the ratio of distance covered to the time taken.

       $Speed =\frac{Distance}{time}$

• Put the given data from the question as time 3 hours and distance  

       120 km.

       $Speed =\frac{120}{3} =40KM/H$

       To convert speed in m/s multiply speed by  5/18

        $Speed=40\times\frac{5}{18} =11.11\frac{m}{s}$

Bus is moving by the speed of  11.11 m/s
