A man travels by a car from town A to town B, a total distance of 100 km at an average speed of x km/h. he finds that the time for the journey would be shorter by 25 minutes if he increases his average speed by 12km/h. Find x ?

Solution :

It is given the that the distance between town A and B is = 100 km

His initial average speed is = x km/h

His increased average speed is = 12 km/h

Time is shortened by = 25 minutes

So according to the question,

$\frac{x \ km/h}{100\ km}-\frac{12 \ km/h}{100 \ km} = 25$

$\frac{x-12}{100}=25$

x-12 = 2500

x = 2512
