Answer:
0.722224 m/s
Step-by-step explanation:
First we need to solve for speed.
Speed = distance/time
We know that velocity is measured in m/s so we plug that in.
We'll define our first velocity as v1 and our second as v2.
Using the formula, we first calculate v1.
Speed = 50m/3min
v1 = 0.277778 m/s
Now we just set that number aside and calculate for v2.
v2 = 1.16667 m/s
Now we have both velocities defined as v1 & v2 we can calculate the average.
So our answer is
(0.277778+1.16667)/2 = 0.722224 m/s
