If different distance is travelled in different time then,
If a car travels 50 Km in 1 hour, another 40 Km in 2 hour and another 70 Km in 3 hour then what is average speed of car.
Total Distance Covered = 50 + 40 + 70 = 160 Km
Total Time Taken = 1 + 2 + 3 = 6 hours.
If equal distance is travelled at different speed.
If equal distance is travelled at the speed of A and B then,
A boy goes to his school which is 2 Km away in 10 minutes and returns in 20 mins then what is boy’s average speed.
Let’s say A = 2/10 = 0.2 km/min
And B = 2/20 = 0.1 km/min
If equal distance is travelled at the speed of A, B and C then,
If a car divides its total journey in three equal parts and travels those distances at speed of 60 kmph, 40 kmph and 80 kmph then what is car’s average speed?
Let’s say A = 60, B = 40 and C = 80, then
