September 2010 Distance Homework

My house is about 19.8 miles away from Parish. We leave every day around seven, and arrive by 7:45. It generally takes about 40 minutes to get from our house to Parish.

This means that our average speed is 29.7 miles per hour, which is approximately 796 meters/minute. I figured this out by:

AVG. SPEED = DISTANCE/TIME (v = x/t)

x = 19.8 miles

t = 40 minutes

v = ?

19.8 miles ÷ 40 minutes = 0.495 miles/minute

x 60 minutes per hour = 29.7 miles/per hour

29.7 MPH = ? meters/per hour

1 Mile ≈ 1609 meters

1609 m x 29.7 mi = 47,787 m

47,787 m ÷ 60 mins = 796 m / minute

47787 x 1 1/3 =
