Calculating Running Distances and Rates

The video tutorial explains how to calculate the distance Heather ran on Thursday based on her running rate from Wednesday. It first determines her rate as 1/10 of a mile per minute, then uses this rate to calculate the distance for a 45-minute run. An alternative method using percentage increase is also discussed, showing that a 50% increase in time results in a 50% increase in distance, confirming the calculated distance of 4.5 miles.

What was the initial distance Heather ran on Wednesday?

• Five miles

• Three miles

• Two miles

• Four miles

How do you calculate the rate of running in this scenario?

• Time multiplied by distance

• Distance multiplied by time

• Distance divided by time

• Time divided by distance

What is Heather's running rate in miles per minute?

• 1/5 mile per minute

• 1/20 mile per minute

• 1/10 mile per minute

• 1/15 mile per minute

How far did Heather run in 45 minutes at the same rate?

• 25%

• 100%

How much is 50% of the initial 3 miles?

• 2.5 miles

• 2.0 miles

• 1.0 mile
