If speed of auto rickshaw increase by 4 km/h, time taken for cover same distance will be 2.25 hours
Step-by-step explanation:
GIVEN
Time = 3 hours
Distance = 36 km
___________________________
TO FIND
If speed of auto rickshaw increase by 4 km/h, time taken for cover same distance
___________________________
We know that,
Speed = Distance / Time
Speed | 36 / 3
Speed = 12
Speed = 12 km/h
At speed of 12 km/h the auto rickshaw will take 3 hours to cover 36 km distance
___________________________
___________________________
NOW,
Speed = 12 + 4 = 16 km/h
Distance = 36 km

TO FIND
Time
___________________________
We know that,
Speed = Distance / Time
Time = Distance / Speed
Time = 36 / 16
Time = 2.25
Time = 2.25 hours
If speed of auto rickshaw increase by 4 km/h, time taken for cover same distance will be 2.25 hours
