Question

A car can travel 120 km in 2 hours.How long will it take the car to travel 300 km?

Answer 1

We first find out time taken to travel for just 1 km

2hrs is equivalent to 120 minutes

120 km  = 120 min

1 km  =  x        (where x is the time taken to travel 1 km).

we simplify the equation by cross - multiplying the equation , so:

120  × x = 1 × 120  → 120x = 120  → x  = 120/120 → x = 1

So  the car covers 1km  in 1 minute

For 300 km the car will take 300 × 1 minute = 300 minutes

we convert minutes to hours by dividing by 60 → 300 / 60 = 5

Therefore the car will take 5 hours to cover 300 km.

Answer 2

First you find the unit rate which is 60 km/ hour. Then You divide 300 by 60 to see how long it will take the car to travel 300 km which is 5
So It Will Take 5 Hours
