It takes a street sweeper 27 minutes to travel 3 miles. If the street sweeper travels at the same speed, how many miles will the street sweeper travel in 45 minutes?

x=5 miles

Step-by-step explanation:

first you have to get his constant speed or his rate

rate = time / distance

so in this case 27/3 which equals 9,

1 mile = 9 minutes

then, you would set up your equation

9 minutes = 1 mile

45 minutes = x miles

cross multiply , 45 * 1= 45 , then divide by 9

x = 5 miles

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
