Problema Solution
Tom Quig traveled 240 miles east of St. Louis. For most of the trip he averaged 60 mph, but for one period of time he was slowed to 20 mph due to major accident. If the total time of travel was 6 hours, how many miles did he drive at the reduced speed?
Answer provided by our tutors
Let x = miles traveled at 20 mph
Then
(240-x) = miles traveled at 60 mph
Using the equation: Time = Distance/Speed we have:
x/20 + ((280 - x))/60 = 6
