Manuel traveled 8 hours nonstop to Mexico, a total of 413 miles. He took a train part of the way, which averaged 60 mph, and then took a bus the remaining distance, which averaged 50 mph. How long was Manuel on the train?
Answer provided by our tutors
let he was in train for x hours:
in bus = 8-x hrs
total distance = 60x + 50(8-x)
=> 10x + 400 = 413
=> x = 1.3 hr
in train = 1 hour and 18 minutes
