Essentially based on the information in the stem we do have a right triangle
Finding the legs means finding the distance that both Wanda (w) and Jeff (J) traveled.You get:
w= 30mph • 2hr = 60mi
j = 36mph • 4hr = 144mi
Using the Pythagorean Theorem
60^2+144^2=c^2
Solve
c=156
Jeff and Wanda are 156 miles away after 4 hours
speed of wanda +speed of jeff = distance traveled
30mph+36mph=156 miles
t=156/66=2.36 hours
Now, the total distance is 60+144+156=360 miles
Total time =4+2.36=6.36 hours
The average speed is 360 miles/6.36=56.6 miles per hour
