Question

A blue whale is swimming at an average rate of 3 miles per hour.

Write a linear equation that gives the distance y in miles that the whale swims in x hours.

Answer 1

y = 3x

Explanation:

you can use the equation to determine how many miles the whale swims in any desired hour

example, if you want to know how far it swims in 5 1/2 hours then just plug 5 1/2 in for 'x' and solve for 'y'

y = 3(5.5)

y = 16.5

whale travels 16.5 miles when going at a rate of 3 mph
