Problema Solution
Her average speed was 8 miles per hour. Today, she went on another ride, this time averaging
14 miles per hour. In the two days, she biked for a combined total time of 13 hours.
Let x be the number of hours she biked yesterday. Write an expression for the combined total number of miles she biked in the two days.
Answer provided by our tutors
Since distance = speed*time we have:
distance = 8x + (13 - x)*14
distance = 182 - 6x miles
The expression for the combined total of miles is 182 - 6x miles.
