Answer 2

$\Large{\underline{\underline{\bf{Solution :}}}}$

☯ Given :

Numner of laps travelled in 10 minutes = 4

$\rule{200}{1}$

☯ To Find :

We have to tell that How long will it take the race car to complete 90 laps ?

$\rule{200}{1}$

☯ Solution :

↪ 4 laps can be completed in 10 mins.

So,

↪ 1 lap can be completed in $\sf{\cancel{10}}{\cancel{4}}$ minutes = 2.5 minutes

$\rule{150}{2}$

Now,

90 Laps must be completed in 90 $\times$ 2.5 minutes

90 laps can be completed in 225 minutes.

→ 3 hours 45 minutes

$\Large{\implies{\boxed{\boxed{\sf{225 \: minutes}}}}}$

$\therefore$ 225 minutes are required by car to complete 90 laps.
