Question

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. What is sped in knots??? Plzzz I will give you 100 points

Answer 1

5 knots

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:

`(miles)/(hour)=(15)/(2.5)=(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:

`(1.2)/(1)=(6)/(x)` where x = the number of knots

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