Well if it is 30 minutes a day 3 days a week and we want to use x to represent weeks we need to find how many hours she tutors a week

rea201 · Answer

So we would have 1.5 hours a week right?

don't forget, you are looking for 30 minutes a day, 3 days a week PER person

yes

rea201 · Answer

Yes so it would be 3 hours a week because there are two students.

Alicia went on a steamboat ride up the Mississippi River. The boat travels 24 miles per hour in still water. How long will it take her to travel 54 miles upstream if the current of the river is 6 miles per hour?

mathstudent55 · Answer

The current will slow down the boat by the current's speed.
The boat travels at 24 mph with no current.
Since the current will slow it down by 6 mph, what is the speed of the boat going upstream?
