Question

if a car covers half of its distance by speed 10 m/s and remaining half by 20 m/s find the average speed​

Answer 1

Explanation:

average speed= total distance covered/total time taken average speed=10+20/2=30/2= 15.

Answer 2

Answer:

Given : V1 = 10 m/s

V2 = 20 m/s

Distance = d = 2m

therefore,

• average speed = speed 1+ speed 2 / distance covered
• average speed = V1+V2 / d
• average speed = 10+20 / 2
• Average speed = 30/2 = 15 m/s
