Homework Equations


N/A


The Attempt at a Solution


66mph for 30mins= 33miles, 27mph for 4min= 20.25miles, and 0mph for 20min= 0miles

33+20.25+0= 53.25miles

Find the total travel time and divide.
 
  • #3
95min/53.25= 1.78mph... that seems to slow
 
  • #4
What units was the time in the denominator expressed in?
 
  • #5
divide 95 by 60 to get the answer in hours...

53.25miles/1.58hrs= 33.64mph
 

1. What is the formula for calculating average mph?

The formula for calculating average mph is: distance / time.

2. How do you convert the units for average mph?

To convert the units for average mph, divide the distance in miles by the time in hours.

3. Can you calculate average mph using kilometers and minutes?

Yes, you can calculate average mph using kilometers and minutes. First, convert the distance in kilometers to miles by multiplying it by 0.62137. Then, divide the time in minutes by 60 to get the time in hours. Finally, use the formula distance / time to calculate the average mph.

4. What is considered a good average mph for running?

A good average mph for running can vary depending on a person's fitness level and goals. However, a general guideline is that a pace of 6-7 mph is considered a moderate jogging pace, while a pace of 8-9 mph is considered a moderate running pace.

5. How can I improve my average mph?

To improve your average mph, you can try incorporating interval training, increasing your mileage gradually, and focusing on proper running form. Consistency and patience are key in improving your average mph.
