Question 1014427
 harry drove for 3 hours on the freeway then decreased his speed by 20 miles per hours, and drove 4 more hours on a country road. If his total trip was 291 miles then what was his speed on the freeway?
----
3x + 4(x-20) = 291
7x - 80 = 291
----
7x = 371
x = 53 mph (speed on the freeway)

Cheers,
Stan H.
