Question

One day, ramesh started 30 minutes late from home and driving at 25% slower than the usual speed, reached the market 50 minutes late. How much time in minutes does ramesh usually take to reach the market from home?

Answer 1

Answer:

Ramesh usually takes 60 minutes of time time to reach market from home.

Explanation:

Let the usual speed of Ramesh is u

and the usual time taken by him is t minutes

Now, ramesh started 30 minutes late from home and driving at 25% slower than the usual speed, reached the market 50 minutes late.

Therefore,

The time taken by him to reach market is: 50-30= 20 minutes

Now as his speed is  25% slower than usual

it means u x 25%= 0.75 u

and the time by him is (t+20) minutes

hence the usual speed is:

t x u= (t+20) x  0.75 u

or, 15= 0.25t

or, t= 60
