Question

The distance Ahmedabad and Vadodara is hundred kilometre. A man drove his car from Vadodara to Ahmedabad in two and a half hours. Calculate the speed of the car.

Given

  • Distance between Amedabad and Vadodara is hundred kilometre.
  • A man drove his car from Vadodara to Amedabad in two and half hours.

Required to Find

The speed of car

Solution

We know,

 \sf \: speed \:  =  \frac{distance}{time}

 \sf \: distance = 100km

 \sf \: time = 2 \frac{1}{2} hours =  (\frac{5}{2} )hours

Therefore,

 \sf \: average \: speed =  \frac{100}{ \frac{5}{2} } km/hr

 \sf \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  = 100  \times  (\frac{2}{5} )km/h

 \sf \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  = 40km/h

Hence, the speed of the car was 40km/h
