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
