Answer:
A: r = d/t B: 380,160 C: 216 D: miles/hour
Step-by-step explanation:
A: d = rt
Rearrange by dividing both sides by time(t)
d/t = r
B: d = 760,320 yards
t = 2 hours
r = d/t
r = 760,320 / 2
r = 380,160 yards/hr
C: 1 mile = 1760 yards
760,320 / 1760 = 432 miles
r = 432 / 2 = 216 miles/hour
D: It makes more sense to use miles per hour in this situation because it is the unit of measurement commonly used for measuring a vehicle's rate.
