To find mi/hr, divide the miles by the hours.
Is that not obvious?

:
a. What was the riders’ average speed to the nearest tenth of a mile per hour?
speed = dist/time
s =
s = 8.2 mph
:
b. A student estimates that it would take a Pony Express rider less than
6 hours to travel 75 miles.
Is the student’s estimate reasonable? Explain
Make a proportion out of this.
let t = actual time to go 75 mi
=
cross multiply
1966t = 240 * 75
t = 18000/1966
t = 9.15 hrs to go 75 mi
:
:
Check: 8.2 * 9.15 = 75 mi
