Question

. A car travels 120 km in 2 hours 30 minutes.

(a) How much time will it require to cover 40 km with the same speed?​

Answer 1

Answer:

It is a case of direct variation because the distance is decreased, the time taken will also decrease.

120x = 40 * 2.5

120x = 100

x = 100/120

x = 5/6 hrs = 50 minutes
