]Answer:
Step-by-step explanation:
Substitute the value of the variable into the equation and simplify.
Solve it out.
Multiply / divide / add / subtract everything out.
To find the average speed for the whole race, you just have
to add the speed from a starting marker and the speed from the turnaround
marker going back and divide it by 2 since there are only two speeds involved.
10 m/s + 16m/s = 26 m/s / 2 = 13 m/s
Therefore, the average speed for the whole race is 13 m/s.
