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, 10 laps it takes 12 × 10 min = 120 min

= 2 hours

The time is taken = 2 hr
