A car travels 20 km per hour in first 40 km in second hour and 30 km hour.

Calculate the average speed car.

Answer :

Speed in first hour = 20 km

Speed in second hour = 40 km

Speed in third hour = 30 km

$average \: speed \: \ = \\ \ \frac{total \: distance \: travelled}{total \: time \: taken} \\ \\ \frac{20 + 40 + 30}{3} \\ \frac{90}{3}$

30 km/hr
