Answer 1

ANSWER:

The car will take time of 5/6 hour or 50 minutes to cover 30 km

EXPLANATION:

We know Speed = distance/time

First we have to find out the speed of car

Distance = 90 km

Time = 2 and a half hour = 2.5 hours

Speed of car = 90/2.5 = 36 km /hr

Now new distance = 30 km

Speed = 36 km/hr

Time = to find out

Time = distance /speed

Time = 30 km/36 km per hour

Time = 5/6 hour

Time = 5/6 × 60 minutes

Time = 50 minutes

The car will take time of 5/6 hour or 50 minutes to cover 30km
