Correct Answer - Option 2 : \(\frac{3}{2}\) hours

Given:

A car travels at a speed of 60 km/hr for one hour.

The speed of a second car is 40 km/hr.

Formula Used:

Speed = Distance/ Time

Calculation:

A car travels at a speed of 60 km/hr for one hour.

Speed = Distance/ Time

⇒ 60 = Distance /1 

⇒ Distance covered by a Car in 1 hour = 60 km.

The speed of a second car is 40 km/hr.

Speed = Distance/ Time

⇒ 40 = 60/Time

⇒ Time taken by second car = 60/40 hours.

⇒ Time taken by second car = 3/2 hours.

∴ The second car will take 3/2 hours to cover the distance.
