Question

A bus travels a distance of 186 km in 2hour 35 minutes. What is the speed of the bus in km/hr

Answer 1

Here your answer goes

Step :-1

Convert km into m

186 km = 186000 m

Convert time into second

2 hours 35 minutes = 9300 second

Step :- 2

We know that ,

Speed =$\frac{Distance}{Time}$

$\frac{186000}{9300}$

20m/s

Step :- 3

Convert  into km/hr

20 *$\frac{18}{5}$

⇒ 72 km/hr

Therefore , the speed of the train is 72 km/hr

Answer 2

Given:

Distance traveled = 186 km

Time = 2 hours and 35 minutes

Now note that changing this to meter and seconds will be very lengthy

So:

change the 35 minutes into hours.

1 minute is 1/60th of an hour

35 minutes is 35/60th ==> 7/12 th of an hour.

So:

2 hours + 7 / 12 th of the hour

==> 2 + 7 / 12

==>( 24 + 7) / 12

==> 31 / 12 hours

Speed = Distance / time

==> 186 km / (31 / 12) hours

==> (186 km /31  )* 12 /hours

==>  6 * 12 km / hr

==> 72 km / hr

The speed of the bus in km / hr is 72 km /hr
