Graham drove 42 1/3 miles in 1 1/3 hours. How many miles did he drive in one hour?

127 miles

Step-by-step explanation:

60 / 3 = 20.

If he drove 42 1/3 miles for 20 mins, all you have to do is multiply the distance by 3 to get the total distance in an hour.

42 1/3 * 3 = 127

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.
