Going against the current, a boat takes 6 hours to make a 120-mile trip. when the boat travels with the current on the return trip, it takes 5 hours.

if x = the rate of the boat in still water and y = the rate of the current, which of the following expressions represents the rate of the boat going with the current?

x - y
x + y
xy

Step-by-step explanation:

Given: Going against the current, a boat takes 6 hours to make a 120-mile trip. When the boat travels with the current on the return trip, it takes 5 hours.

Clearly , it can be seen that when boat travels with current , it takes competitively less time.

i.e. the speed of the boat would increased by the current.

If x = the rate of the boat in still water and y = the rate of the current, then the expressions represents the rate of the boat going with the current will be :-

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
