Question

a car increases its speed from 20 km/h to 50 km/h in 10 seconds find its average speed​

Answer 1

Answer:

i am going to give you the average velocity

Explanation:

average velocity = v+u/2

(Here u is initial velocity and v is final velocity)

Therefore average velocity =50km/h+20km/h/2

let us first convert 50 km /h and 20km/h to m/s

50000m/3600s and 20000m/3600s

Therefore 50000+20000/2

= 70000/2 = 35000m/s

Thankyou
