lower end speed:
so far --- time = 70/50 = 1.4 hrs
total trip -- time = 154/50 = 3.08 hrs
top end speed:
so far --- time = 70/57 = 1.23 hrs
total trip -- time = 154/57 = 2.701 hrs
I don't see a " which of the following" part , so use my results above to match with your choices
remember, you want the "time remaining", I have time used so far and total.
So what do you think you should do with my answers ?
