Problema Solution
a bus traveled on a level road for 5 hours at speed that was 15 mph faster than the speed when traveling ona winding road . the time spend on the winding road was 3 horus. what is the speed of the bus on the winding road if the bus trip was 395 miles?
Answer provided by our tutors
let
v = the speed on the winding road
v + 15 = the speed on the level road (15 mph faster than the speed when traveling on a winding road)
t1 = 5 hr the time the bus traveled of the level road
t2 = 3 hr
d = 395 mi
since distance = speed*time we have:
v*t1 + (v + 15)*t2 = d
5v + (v + 15)3 = 395
by solving we find:
v = 43.75 mph

the speed of the bus on the winding road is 43.75 mph.
