Question

A car covers a distance X in 20s while moving at a speed of 50km h -1 (power). Find (a) the total distance covered by a car by the car(b) average speed of the car.

Answer 1

Answer:

a)276m      b)13.8m/s

Explanation:

a)Distance(d)= x metre

Time(t)= 20s

speed(s)=50km/h= 13.8m/s

d=s*t

  =>13.8*20= 276m

b) Average speed= total distance covered

                                 total time taken

                              =>$\frac{276}{20}$= 13.8m/s
