Problema Solution
During a hurricane evacuation from the east coast of Georgia, a family traveled west. For part of the trip, they averaged but as the congestion got bad, they had to slow to If the total time of travel was 7 hours, how many miles did they drive at the reduced speed?
Answer provided by our tutors
Let x be the travel time at 50mph
50.x + 20 (7 - x) = 260 miles
50 x + 140 - 20 x = 260
30 x = 120
x = 4
So at 50mph, family traveled 200 miles
At 20mph family traveled 60 miles.
