A boat takes 2 hours to travel 15 miles upriver against the current. If the rate of the boat in still water is 13 miles per hour what is the rate of the current?

The rate of the current is 5.5 miles per hour

Step-by-step explanation:

Relative Speeds

The boat takes 2 hours to travel 15 miles upriver against the current. The speed is 15/2 = 7.5 miles per hour.

Since the boat in still water can travel at 13 miles per hour, it means the current subtracts its speed from the speed of the boat:

Vcurrent = 13 mi/h - 7.5 mi/h

Vcurrent = 5.5 mi/h

The rate of the current is 5.5 miles per hour

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
