A car race travles at constant speed. it can complete 4 laps of race course in 48 miuntes.

how long dose it take to complete 10 laps?

It takes 2 hours to complete 10 laps.

Step-by-step explanation:

Given,

A car completes 4 laps in 48 min

To find the time it takes to complete 10 laps.

Method

We will apply the unitary method to solve it.

For 4 laps it takes 48 min

For 1 lap it takes (48:4) min = 12 min

For, 10 laps it takes 12 * 10 min = 120 min

= 2 hours

The time is taken = 2 hr

It takes 2 hours to complete 10

Laps.

48/4 is 12 so it's it 12 minutes a lap

12x10 is 120 which equals out to 2 hours
