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.
