Answer 2

Step-by-step explanation:

A car takes 6 hours to cover a distance at a speed of 60 km / hr

the speed is decreased by 20 km / hr

= 60 - 20 km / hr = 40 km / hr

time taken by car to cover 40 km / hr = 60×6 ÷40

= 9 hr

so, the car will take 9 hrs to cover a distance at a speed of 40 km / hr.
