Question

An object began moving at the starting point (0,0) on the graph. The average speed of the object for the entire trip of 5.0 hours is:

A. 15mph
B. 17mph
C. 19mph
D. 20.0mph
E. 22mph

Answer 1

B 17


85 ÷ 5 would be the equation you do to solve

Answer 2

Answer: So in your graph, you can see that after 5 hours, the object is in 85m. So your displacement over the lapse of 5 hours in 85m (because the object starts at 0m), the average speed will be distance over time, so 85m/5h=17m/h

So the correct answer is B, 17 meters per hour.
