On the way, the bus driver drives the speed limit for
2 hours when suddenly the bus breaks down. After half
an hour, another bus arrives. Then they travel more
slowly than the speed limit for 1 more hour.
Part A
Sketch a graph to represent the bus trip over time. 1 point
Distance
Part B
Time
Label the intervals on the graph. Describe the behavior of the function in
each interval, and tell what it means in the problem situation. 2 points

step-by-step explanation:

do you have a copy of the table?

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

the answer is 40.

proof:

a reflection across the x axis and a 90 degree rotation left and right.
