A bus began a trip at 9:50 A. M. and arrived at its destination at 1:10 P. M. If the trip was 150 miles long, what was the average speed of the bus for the trip? 35 miles per hour
40 miles per hour
45 miles per hour
50 miles per hour

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

ummm seems that u didnt post the attachement !
