Knots are a unit of speed used for sailing. 1 knot is equal to 1.2 miles per hour. Jesse travels 15 miles by boat in 2.5 hours.

Alinara [238K]

Answer:

5 knots

Step-by-step explanation:

In order to find the speed Jesse travels in knots, you need to find his unit rate, or miles per hour. Setting up a fraction and dividing will give you how many miles her traveled per hour:

$\frac{miles}{hour}=\frac{15}{2.5}=\frac{6}{1}or6mph$

Since Jesse traveld at 6mph, you can set up a proportion (equivalent ratios) using the ratio of 1 knot to 1.2 miles per hour to find the number of knots in 6mph:

$\frac{1.2}{1}=\frac{6}{x}$ where x = the number of knots

cross-multiply and divide: 1.2x = 6 or x = 5 knots
