Imagine that you take a road trip from a to d, but you have to do it in segments. let’s say the distance from a to b is 145 miles; from b to c is 160 miles, and c to d is 115 miles. it takes you 6 hours to drive from a to d. what was your average speed (in miles per hour) during your trip from a to d? (hint: how many miles did you drive from a to d? then divide the total miles by the number of hours).
a. 50
b. 60
c. 70
d. 80
e. 90
