Answer:
Step-by-step explanation:
Remark
The best way to do this is to set up a proportion. It can be done by using d = r * t twice, but a more direct way is to use the proportion.
Formula
distance1 / time1 = distance2 / time2
Givens
distance1 = 696 miles
time1 = 12 hours
distance2 = 522 miles
time2 = x
Solution
696/12 = 522/x Cross multiply
696 * x = 522* 12 Combine the right
696 * x = 6264 Divide by 696
x = 6264/696
x = 9 miles
