Car A and car B both travel 1320 miles. Car A drove at an average speed of 10 miles per hour faster than car B and made the trip in one hour less time. Find the average speeds of both cars.

Solution

(x+10)*(t-1)=1320
xt=1320
x=110
y=12
120*11=110*12
I want to know where they were able to drive for so long at such high speeds.
the Baja 1000?
120 mph for 11 hours
and 110 mph for 12 hours
