Step-by-step explanation:
All you need to do is divide cost by mile since they already factored in the additional $3 for you.
1. 8/5 = $1.60
2. 11/8 = $1.375 = $1.38
3. 23/20 = $1.15

step 1
Find the measure of angle A
Applying the law of cosines


![cos(A)= [215^{2}+125^{2}-185^{2}]/(2(215)(125))](https://tex.z-dn.net/?f=cos%28A%29%3D%20%5B215%5E%7B2%7D%2B125%5E%7B2%7D-185%5E%7B2%7D%5D%2F%282%28215%29%28125%29%29)


step 2
Find the measure of angle B
Applying the law of cosines


![cos(B)= [215^{2}+185^{2}-125^{2}]/(2(215)(185))](https://tex.z-dn.net/?f=cos%28B%29%3D%20%5B215%5E%7B2%7D%2B185%5E%7B2%7D-125%5E%7B2%7D%5D%2F%282%28215%29%28185%29%29)


step 3
Find the measure of angle C
Applying the law of cosines


![cos(C)= [125^{2}+185^{2}-215^{2}]/(2(125)(185))](https://tex.z-dn.net/?f=cos%28C%29%3D%20%5B125%5E%7B2%7D%2B185%5E%7B2%7D-215%5E%7B2%7D%5D%2F%282%28125%29%28185%29%29)


He travels 620miles at the same speed.
Given that joe travels 434 miles in 7 hours.
An object's speed is determined by how quickly it moves. It is the distance a body travels in one unit of time.
Firstly, we will find the speed when the distance is 434 miles and the time is 7 hours by using the formula
Speed=Distance/Time
Substitute the values in the formula, we get
Speed=434miles/7 hours
Speed=62 miles/hour
Now, we will find the distance when time is 10 hours, we get
62=distance/10
Multiply both sides by 10, and we get
62×10=(distance/10)×10
620miles=distance.
Hence, in 10 hours at the same speed, he travels when joe travels 434 miles in 7 hours is 620miles.
