Emily is mowing her lawn which is in the shape of a rectangle with a length of 10 feet and width of 12 feet. Emily completed mow ing it in 3 hours. What is the unit rate at which Emily mowed her lawn?
2 answers:
So what you do first is find the area of this lawn and you do 10 by 12 and multiply those and you get 120 feet so now what you do is divived 120 by 3 and you get 40 so that means she mowed 40 ft in each hour so that would be the unit rate.
Step by step explanation:
Given that,
The shape of the lawn is rectangular
Length of the lawn = 10 feet
Width of the lawn = 12 feet
Time to complete mowing = 3 hours
Rate = ?
Step 1: find the area of the lawn
Area of rectangle is
A = l * w
10* 12 = 120 Feet
Area / no of hours for the mowing to complete
120/3 = 40
This meant that the rate at which Emily mowed her lawn is 40 ft per hour
