Answer 2

Given:

We have given that A car covers 40 km in first hour, 115 km in next two hours and 45 km in next one hours.

To Find:

We have to find the average speed?

Explanation:

• Speed of any vehicle or anything is given by the formula dividing the term distance by time.
• For calculating the average speed of the car first of all we will find the total distance covered by car.

• We have tree distance measured one is 40km and 115 km and 45km.

       $\textrm{total distance}=40+115+45=200km$

• Now we will find the total time taken by the car to travel the given distance.

        $\textrm{total time}=1+2+1=4$

• Thus, the average speed of the car will be calculated by dividing the total distance by total time.

        $\textrm{Average speed}=\frac{\textrm{total distance}}{\textrm{total time}}$

• Now, we will put the values total distance is 200km and total time is 4hour in the above equation.

       $\textrm{Average speed}=\frac{200}{4}=50$

Hence, the average speed of the car is 50 km per hour.
