To find: the speed at which Allison is rowing and the speed of the boat.
a.
Answer to Problem 50PPS
Explanation of Solution
Given:
Allison can go in upstream at
Calculation:
First, we need to understand how many minutes it takes Allison to row a mile without the influence of the current, to do so it need to make two equations. One showing the time against the current. After that, it will eliminate and solve for X, or Allison, to discover how long it will take to row a mile.
So, it takes Allison 18.5 minutes to row a single mile without the aid or hindrance of the current. With this information, it can also find Allison rough speed as 3.24 mph. to find the speed of the current, it must take the time, it takes Allison to go a mile against the current, 24 minutes, divide it into 60 to give us a mph basis, 2.5, and then subtract 2.5 from 3.24. this gives 0.74 as the current speed.
Thus, the speed at which Allison is rowing and the speed of the boat is respectively
b.
To check: whether the Samantha has enough money to cover the fare.

Answer to Problem 50PPS
Explanation of Solution
Given:
Allison can go in upstream at
Calculation:
Allison takes 1 mile upstream for 24 minutes. If she would travel 3 miles upstream, it will take 72 minutes before it can make it to meet the friends. She would be late for the meet up in an hour because her travel would be one hours and 12 minutes.
