Question 1059012
duane drove 265 miles in 5 hours. part if his trip was on the highway at 55 mph. the rest was in town at 35 mph. how long did he drive in town?
---------
d = r*t
t = d/r
---
h = distance on highway
5 = h/55 + (265-h)/35
1925 = 7h + 11*(265-h) = -4h + 2915
4h = 990
h = 247.5 miles on the highway
--> 17.5 miles in town
==============
17.5/35 = 0.5 hours in town
