How far does the car drive?

Answer 1

Answer:

speed=90 km /h

time =2hrs and 20 min or 2.20 hrs

so speed =distance travelled / Time taken

distance =time taken× speed

distance= 2.20×90

distance=198km

Answer 2

Given:

Speed = 90 km/h

Time = 2 hours 20 mins

To Find:

The distance that the car can cover

Formula Needed:

$\text{Distance} = \text{Speed} \times \text {Time}$

Solution

Convert the time to hours only:

Since the speed is given in km per hour, the time used must also be in hours.

$2 \text { hours } 20 \text { mins } = 2 \dfrac{20}{60} \text{ hours}$

$2 \text { hours } 20 \text { mins } = 2 \dfrac{1}{3} \text{ hours}$

Find the distance covered by the car:

So now, we can simply apply the formula to find the distance.

$\text{Distance} = \text{Speed} \times \text {Time}$

$\text{Distance} = \text{90} \times 2\dfrac{1}{3}$

$\text{Distance} = \text{90} \times \dfrac{7}{3}$

$\text{Distance} = 210 \text { km}$

$\boxed { \text{Answer : } 210 \text { km}}$
