The speed of a river current is 2 mph. if a boat travels 30 miles downstream in the same time that it takes to travel 20 miles upstream, find the speed of the boat in still water. the speed of the boat in still water is blank mph.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
