### Boat speed was calculated like this:

Step 1

First we need to calculate the variable w. w = boat weight in kilograms.

Step 2

Then we need to calculate the variable pw. pw = total passenger weight in kilograms.

Step 3

Then we need to calculate the variable tw. tw = total weight in kilograms.

Step 4

Then we need to calculate the variable mph. mph = boat speed in miles per hour.

Step 5

Finally we put it together and calculate it like this:

### Boat speed was calculated like this:

### Variables used in this formula

d = Total boat weight in kilograms
