Subject: How Much Road Was Under Construction?

Adam made a trip to see his college friend. The college is 295 miles
from Adam's house. He averaged 50 miles per hour (mph)) for most of
the trip but only 40 mph for the part where the road was under
construction. If the trip took 6 hours, how many miles of the road
were under construction?

Here's a suggestion for getting started on this problem. Concentrate
first on the times needed for the two parts of the trip.  Once you
have the times, then you can figure out the two distances.

parts of the trip, then T1 + T2 = 6.  The distances travelled during
the two parts of the trip would be 50*T1 and 40*T2.  You can form
these two into an equation and then solve the two equations in two
unknowns.  Okay?
