Question

plzz make it fast. I am getting 10
m/s but the ans. is 7.5m/s​

Answer 1

Answer:

7.5m/s

Explanation:

so the velocity is distance by time. (v=dx/dt)

here a graph is given which represents a motion,

so you have to find a slope. to find slope,

m=(y-y1)/(x-x1)

m=(50-20)/(4-0)

=7.5 m/s
