Question

a car move at a speed of 20 km per hour for 15 minutes and then at a speed of 60 km per hour and for next 15 minutes. calculate the total distance covered by the car.​

Answer 1

Answer:

Your Answer :-

Distance = S × T = 20 × 1/4 = 5 km. Distance = S × T = 60 × 1/4 = 15 km.

Answer 2

Answer: 20 km

Explanation:

Given:

Speed of the car for the first 15 minutes = 20 km/hr

Speed of the car for the next 15 minutes = 60 km/hr

Find:

The total distance covered by the car.

Solution:

First, we will find out the distance covered by the car in the first 15 minutes.

As we know,

⇒60 minutes = 1 hour, so

⇒15 minutes = $\frac{15}{60}$ hour

Distance covered = Speed × Time taken

Therefore, distance covered = 20 × $\frac{15}{60}$

                                                = 5 km

Now, we will find out the distance covered by the car in the next 15 minutes.

Therefore, distance covered = 60 × $\frac{15}{60}$

                                                = 15 km

The total distance covered by the car = ( 5 + 15) km

                                                                = 20 km

Answer:

The total distance covered by the car is 20 kilometers
