Traveling equation

Question

Manuel traveled 7 hours nonstop to​ Mexico, a total of 378 miles. He took a train part of the​ way, which averaged 60​mph, and then took a bus the remaining​ distance, which averaged 30mph.

How long was Manuel on the​ train?

Answer 1

5 hours and 36 minutes on the Train

60T + 30(7-T) = 378

60T-30T = 378 -210

30T = 168

T =168/30 = 5.6 hours by Train = 5 hours & 36 minutes

5.6x60 = 336 miles on the Train

1.4 hours on the bus

1.4x30 = 42 miles on the Bus
