I cant Figure this out...
Find each Unit Rate:
Four pounds of apples cost $1.96
and
Sal washed 5 cars in 50 mins
Divide.
1.96 divided by 4 = how much one pound of apples costs
50 minutes divided by 5 = how much time (average) it takes to wash one car
To find the unit rate, you need to determine the quantity of one item in relation to the given quantity or cost. Let's start with the first problem:
Four pounds of apples cost $1.96.
In this case, we are given the cost of four pounds of apples, which is $1.96. To find the unit rate, we need to determine the cost for one pound of apples.
To do this, we divide the total cost by the quantity of apples. In this case, our total cost is $1.96, and the quantity is four pounds. So the unit rate is $1.96 divided by 4 pounds.
Unit Rate = Total Cost / Quantity
Unit Rate = $1.96 / 4 pounds
Unit Rate = $0.49 per pound
Therefore, the unit rate for apples is $0.49 per pound. This means that each pound of apples costs $0.49.
Now, let's move on to the second problem:
Sal washed 5 cars in 50 minutes.
Here, we know that Sal washed five cars in a certain amount of time. To find the unit rate, we need to determine how many cars Sal washed in one minute.
To do this, we divide the total number of cars by the time taken. In this case, the total number of cars is five, and the time taken is 50 minutes. So the unit rate is 5 cars divided by 50 minutes.
Unit Rate = Total Cars / Time Taken
Unit Rate = 5 cars / 50 minutes
Unit Rate = 0.1 cars per minute
Therefore, the unit rate for Sal washing cars is 0.1 cars per minute. This means that Sal washes 0.1 (or 1/10th) of a car in one minute.
I hope this helps you understand how to find unit rates. Let me know if you have any more questions!
