Question

average speed formula when time is same distance is different​

Answer 1

Answer:

When a body moves with different speed but for an equal duration in each time then the average speed of the entire journey is the Arithmetic mean of all the speeds.

Step-by-step explanation:

Example: Rahul travels with the speed of 20 km per hour for the first 2 hours. For the next two hours, he travels with a speed of 30 km per hour. Find the average speed of his entire journey.

SOLUTION:

Total distance travelled = 20×2+30×2=100 kilometers

Total time taken =2+2 = 4 hours

Therefore, the average speed=100/4=25 kmph.
