The excursion boat on the river takes 2½ hours to make the trip to a point 12 miles upstream and to return. if the rate at which the boat travels in still water is 5 times the rate of the river current, what is the rate of the current? which of the following equations can be used to solve for c, the rate of the current? no answer choices

Step-by-step explanation:

Let c miles per hour be the rate of the river current. If the rate at which the boat travels in still water is 5 times the rate of the river current, then the rate of the boat is 5c miles per hour.

1. Upstream the rate of the boat is 5c-c=4c miles per hour. To overcome 12 miles upstream it is needed

2. Downstream the rate of the boat is 5c+c=6c miles per hour. To overcome 12 miles downstream it is needed

2. The total time is

If the excursion boat on the river takes 2½ hours to make the trip to a point 12 miles upstream and to return, then

Solve this equation:

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
