Tara has driven 70 miles of a 154 mile trip. If she averages between 50 and 57 miles per hour, which of the following is a reasonable amount of time it will take her to complete the trip?

2 answers

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 ?
Please can you tell me which method should I use to solve probability because I don't understand how to solve probability for grade 6
