Problema Solution
Manuel traveled 4 hours nonstop to Mexico, a total of 186 Miles. He took a train part of the way , which averaged 60MPH and then took a bus the remaining distance, which averaged 30MPH. How long was Manuel on the train?
Answer provided by our tutors
let
t = the time on the train
4 - t = the time on the bus
since distance = average speed * time, we have
60t + 30(4 - t) = 186
by solving we find
t = 2.2 hr
t = 2 hr 0.2*60 min
t = 2 hr 12 min
