If you would like to know how many kilometers will a jet travel in 2 hours (and in 6 hours), you can calculate this using the following steps:
60 kilometers ... 5 minutes
x kilometers = ? ... 2 hours = 120 minutes
60 * 120 = 5 * x
x = 60 * 120 / 5
x = 1440 kilometers
60 kilometers ... 5 minutes
y kilometers = ? ... 6 hours = 360 minutes
60 * 360 = 5 * y
y = 60 * 360 / 5
y = 4320 kilometers
The correct result would be 1440 kilometers in 2 hours, and 4320 kilometers in 6 hours.
