Question

A. If a T-Rex runs 20 meters in 4 seconds, what is it’s average speed?

Answer 1

5m/s

100m

Explanation:

Average speed is sum of distance distance traveled in a given time by a body.

 Average speed= $\frac{total distance covered}{time taken}$

Distance = 20m

time = 4s

  Average speed = $\frac{20}{4}$ = 5m/s

For the spaceship;

   Distance covered = speed x time

Speed = 50m/s

time = 2s

 Distance covered = 50 x 2 = 100m
