Topic: St math homework
May 23, 2019 / By Ewane Question:
I have four questions that I really need help with. I am a really good straight A student, but my teacher didn't cover this as much.
Write and Solve an equation for each situation:
Marla begins walking at 3mi/h toward the library. Her friend meets her at the halfway point and drives her the rest of the way to the library. The distance to the library is 4 miles. How many hours did Marla walk?
Fred begins walking toward John's house at 3 mi/h. John leaves his house at the same time and walks toward Fred's house on the same path at a rate of 2mi/h. How long will it be before they meet if the distance between the house is 4 miles?
A train leaves the station at 6:00 P.M. traveling west at 80mi/h. On a parallel track, a second train leaves the station 3 hours later traveling west at 100mi/h. At what time will the second train catch up with the first?
It takes 1 hour longer to fly to St. Paul at 200 mi/h than it does to return at 250 mi/h. How far away is St. Paul?
If you could answer all, or even one of them, that would help a ton... Thanks

How about YOU TRY. Show your work and where you're having problems. Then one of us can HELP by HELPING you understand this. Otherwise, just DOING your work is no HELP.
Sorry, due to lack of time, I can onl answer the first. We know the distance from wherever Marla started from is 4 miles, and she stops halfway to hitch a ride with her friend. That stop point is at the 2 mile point. So in how long does it take for Marla to walk 2 miles at 3miles/hr? Well if it was 3 miles, it would've taken her an hour. But instead, it was 2, meaning it would've taken 2/3 the time to walk an hour, also meaning 2/3 of an hour. 2/3 of an hour, would be 40 minutes
