Define x:
Let the time he traveled by train be x
The time he traveled by plane is also x
By Train:
Time = x
Speed = 55 mph
Distance = Time x Speed
Distance = 55x
By Plane:
Time = x
Speed = 285 mph
Distance = 285x
Solve x:
Given that the total distance is 1020
55x + 285x = 102
340x = 1020
x = 1020 ÷ 340 = 3 hours
Find the total time
Total time taken for the trip = x + x = 2x = 2(3) = 6 hours
