The distance between two bus stops is 5 km. A bus travels the distance in 20 min. What is the speed of the bus? Also, convert it into $\frac{m}{s}$ . Can it also be called as the average speed of the bus?

Given: the distance between two bus stops is 5 km. A bus travels the distance in 20 min

To find: the speed of the bus, speed also in $\frac{m}{s}$

Solution:

Distance between bus stops = 5 km

Time taken to cover 5 km = 20 min = $\frac{20}{60}hr$ =  $\frac{1}{3}hr$

Speed of bus = $\frac {Distance}{time}$ =$\frac {5}{\frac{1}{3}}$ = $15 kmph$ 

Speed in $\frac{m}{s}$ = $15 kmph$ $\times \frac {5}{18}$ = $4.17$ $\frac{m}{s}$

So Speed of bus =
