solving applications using rational expressions

A rowing team rowed 90 miles while going with the current in the same amount of time as it took to row 10 miles going against the current. The rate of the current was 4 miles per hour...

Hint: Use the formula v= d/t

(6x^2 -3x+5) /(2x-3)

John takes 2 hours longer than Andrew to peel 600 pounds of apples. If together they can peel 600 pounds of apples in 8 hours, then how long would it take John to peel the apples working alone?

(4x+1)/(x—8) — (2)/(x+2) — (8x+16)/(x^2—6x—16)

Bob drove 120 km in traffic. On the returning trip, he drove twice as fast. The total time was 4 hours. What was the rate for each direction?

Just need answer and explanation why?

You recently bought and planted some pea shoots. So far they have grown 5 inches in a week. At that rate, how much will they have grown at the end of 30 days?

a canal has a current of 2 mph. find the speed of Vanessa's remote-controlled boat in still water if it would go 11 miles downstream in the same time that it goes 8 miles upstream.

A cheetah can run 20 miles per hour faster than a lion. A cheetah can run seven miles in the same time that a lion can run 5 miles. Find the speed of each animal.

(1/x)=(1/(4-x))

(1/(x+3)) - (x/(x2-9))=-(2/(x-3))

Solve this problem using five steps for problem solving (familiarize, translate, carry out, check, state). You recently bought and planted some pea shoots. So far they have grown 5...

evaluate the expression for x=1/2 (x2 - 4)/(x2+4)

find the values of x for which this expression is undefined: (x2 - 4) / (x2 + 4)

simplify this expression: (t3 - 9t) / (t(t+3)3) ----------------------------------------------------------------------------------------------- Consider the expression (x2...

find the values of t for which the expression is undefined: (t3 - 9t) / (t(t+3)3)
