A wandering tapir trots along at 9 ft/s for 9 minutes, then walks at 6 ft/s for 7 minutes, and finally runs at 27 ft/s for 1 minutes. How do I find the average speed of the tapir ?

I have already added the numerators and denominators then divided by 3

Average speed = total distance traveled divided by the time it took.

Break it into 3 sections,
distance1 = velocity1 * time1, distance2 = ..., distance3 = ...
add those 3 together to get the total distance, then divide by the total time to get the average speed.
