Question

A car drives at a speed of 90 km/h for two hours and 20 minutes how far does the car drive?

Answer 1

Answer:

Step-by-step explanation:

There is 60 minutes in an hour.

Therefore 40 minutes / 60 minutes narrows down to 2 / 3

One way to solve this would he cross multiplying.

2 . X

_ = _

3 . 90

To cross multiply you multiply the 2 diagonals and divide by the other number to solve the variable X or the answer.

90 × 2 = 180

180 ÷ 3 = 60

Therefore the car can travel 60 km in 40 mins

You can check your answer by dividing 60 by 90 which reduces down to 2 / 3. Therefore you know your answer is correct. Left side = right side.

Answer 2

Answer:

The distance covered by the car is 210 km.

Step-by-step explanation:

We can calculate the distance covered by car from the below formula.

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

Here,

Speed of car = 90 km/h

Total time = 2 h 20 min = $2\frac{20}{60} =2\frac{1}{3} =\frac{7}{3}\ h$

$Distance= Speed \times Time$

$Distance=90\times \frac{7}{3}$

$Distance= 30\times 7$

$Distance=210\ km$

Therefore, The distance covered by the car is 210 km.
