John rides his bike to work each day. the distance between his house and his work is approximately 6.5 miles, and it takes him on average 45 minutes to get there on his bike. in order to compare the approximate speed of his bike to that of a car, he determines his average speed on the bike in miles per hour. which of the following values most likely represents the value john determined to be his speed on the bike in miles per hour? a 9.0 mph b 8.7 mph c 8.66 mph d 8.667 mph

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 : )
