The speed of a river current is 8 mph. If a boat travels 20 miles downstream in the same time that it takes to travel 10 miles upstream, find the speed of the boat in still water.

9 mph

Step-by-step explanation:

-Let x be the speed of the boat upstream.

-Since the time upstream and downstream is equal, we will equate their time functions to solve for x:

-Speed upstream=x-8

-Speed downstream=x+8

#We then equate as follows:

Hence, the speed of the boat in still water is 9 mph

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
