A boat takes 30 minutes to travel 15 miles upstream and 25 minutes to travel the same 15 miles downstream. Assuming that the boat’s engine is set at the same power setting and the speed of
the current remains constant for both trips, what’s the boat’s speed in miles per minute at that
power setting in still water. You may express your answer in a simple fraction.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
