If a car travels 60 kmph then it reaches the destination in 4 hours. If the car travels at 80 kmph then the time taken by car is ………………. hrs 

A) 10 

B) 4 

C) 6 

D) 3

Answer 1

Correct option is (D) 3

Distance covered by car by travelling 60 kmph in 4 hours = speed \(\times\) time

\(=60\times4\) = 240 km

When car travels at 80 kmph then time by the car \(=\frac{Distance}{Speed}\)

\(=\frac{240}{80}\) = 3 hours

Answer 2

Correct option is  D) 3
