Question 161603
.
Let x = time traveled by plane
then
2x = time traveled by train
.
Applying distance formula to calculate distance traveled by each:
48(2x) + 240x = 1200
96x + 240x = 1200
336x = 1200
x = 3.57 hours (time traveled by plane)
.
2x = 2(3.57) = 7.14 hours (time traveled by train)
.
total time: 10.71 hours
