Question

a car travels 20 km in 1 hour and another 40 km in 3 hours what is the average speed of the car ​

Answer 1

As per the definition of average speed, it is basically total distance travelled divided by total time taken

$Average$$speed$ $=$$Total$$distance$ $/$  $Total$$time$

Here total distance travelled is 20+40= 60Km by the car.

Total time taken is 1+3=4hrs.

Hence the average speed of the car is given by

S = 60/4 = 15Km/hr
