Question 1175277

Practice Age word  Problem

Ariana started biking to the library traveling 14 mph, after some time the bike got a flat so Ariana walked the rest of the way, traveling 7 mph. If the total trip to the library took 11 hours and it was 119 miles away, how long did Ariana travel at each speed?
<pre>Let the time she spent biking be T
Then time she spent walking = 11 - T
We then get the following DISTANCE equation: 14T + 7(11 - T) = 119
14T + 77 - 7T = 119
14T - 7T = 119 - 77
7T = 42
Time she spent biking, or {{{highlight_green(matrix(1,6, T, "=", 42/7, "=", 6, hours))}}}
Should now be extremely easy for you to find the time spent walking!
