Question

how to find average speed without distance and time.
A motor car travels a certain distance with a speed of 40 km/h and returns with a

speed of 30 Km/h. Calculate the average speed for whole journey.​

Answer 1

Answer:

Average Speed. The speed of an object is found out by dividing the distance that the object covers by the time in which the object takes to cover this distance. If 'D' is the distance traveled in some time 'T' then the speed of the object for this journey or 's' is equal to s = D/T. This is the simplest case.
