The train ran at less than its full speed, which means it ran at a fraction of its full speed. That fraction is 7/11, which translates into a decimal of 0.636.

These facts mean that at full speed the train would have reached its destination in less than 22 hours.

Let t = time at full speed

then t = 0.636 x 22 hours

then t = 14 hours

time saved = 22 hours - 14 hours = 8 hours
