Answer 1

Answer:

Given :

• A car travels 20 km in 2 hours and another 40 km in the next 2 hours. Find the average speed of the car.

To find :

• Find the average speed of the car?

Solution :

A car travels 20 km in 2 hrs.

Another travels 40 km in the next 2 hrs.

Let's us find ( the average speed of the car ).

$\sf \bigstar\boxed{\underline \red{ \underbrace {Average \: Speed = \frac{ Total \: distance}{Total \: Time}}} } \bigstar$

Here see The total distance travelled by the car is 20 km + 40 km = 60 km.

Total time taken by the car is 2 + 2 = 4 hrs.

Hence, the average speed of the car is given:-

$\sf \bigstar\boxed{\underline \red{ \underbrace {Speed = \frac{60}{4} = 15km/hrs}} } \bigstar$
