Step-by-step 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

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

Answer 2

Time taken by car is 5 hours and 50 minutes.

Given:

• A car travels 90km in 2 hours 30 minutes.

To find:

• How much time is required to cover 210 km?

Solution:

Formula to be used:

$\bf Speed = \frac{Distance \: }{Time}$

Step 1:

Find the speed of car.

It is given that

Distance $D = 90 \: km$

Time $T = 2.5 \: hours$

So,

Speed

$S = \frac{90}{2.5} \: kmph$

$\bf S = 36 \: kmph$

Thus,

Speed of car is 36 km/hr.

Step 2:

Calculate the time.

The speed of the car is 36 kmph.

Distance travelled 210 km.

Put the values in the formula and calculate the time.

$36 = \frac{210}{T}$

$T = \frac{210}{36}$

$T = \frac{35}{6} \: hours$

$\bf T = 5\frac{5}{6} \: hours$

Convert 5/6 hours in minutes by multiplying by 60.

5/6 hours = 50 minutes.

Thus,

Time taken by car is 5 hours and 50 minutes.
