Question

A bus travels 54km in 90 minutes
Calculate the speed of
the bus
in m/s and also in km/h

Answer 1

answer= 60m/s ,. this is answer

Answer 2

Answer:

A bus travels 54km in 90 minutes then speed of bus is 10m/s and 36km/h

Explanation:

We know

Speed = $\frac{distance}{time taken}$

Speed is rate change of its position with respect of time

In question we have,

Total distance travelled = 54km

Time taken = 90minute

Speed = $\frac{54}{90}$ km/minute

But in question speed asked in m/s and km/hr

So we convert this term

1 km = 1000 meter

1 minute = 60 second

We put values of 1 km and minute in equation

Speed = $\frac{54*1000}{90*60} \frac{m}{s}$

On solving it

Speed = 10m/s

Now we need to convert in km/hr

We know,

1 minute = $\frac{1}{60} hr$

We put value in equation,

Speed = $\frac{54*60}{90} km/hr$

Speed = 36km/hr

Final asnwer

Speed = 10m/s and 36km/hr
