Question

a bus takes 1 hour 30 min to cover a certain distance at a speed of 60 km/hr . How much time will it take to cover the same distance when travelling at a speed of 45 km/hr ?​

Answer 1

Answer:

Speed Of Bus=40 km/h

Time=1 hour 30 minutes.

30 minutes in Hour=30/60=0.5 hours.

Time=1+0.5=1.5 hours.

MEANS Speed=40 km/h

Time=1.5 hours.

Distance=Speed × Time

=40×1.5

=60 km

We know Distance=60 km

Now If Bus speed =45 km/h

Distance=60 km

Time=Distance/Speed

=60/45

=4/3 hours

In Mixed Fraction

=1 1/3  

MEANS 1 hour 1/3 of hour

1 hour=60 min

1/3=1/3×60=20 minutes

Time=1 hour 20 minutes
