Question

what will be the average speed of a car if it has travelled 50 kilometre per hour and 60 kilometre per hour​

Answer 1

Answer:

Explanation:

case 1: Car is moving with a constant speed of 50km/h

case 2: Car is moving with a constant speed of 60km/h

Average speed of the car in entire trip = sum of the two speeds in case 1 and case2 /2

                                           =60+50/2

                                           =110/2

                                           =55 km/h
