In this lab, you will calculate the average speed for five
snowmobiles. The time it takes each snowmobile to travel a certain distance
is listed below. Transfer this information for each snowmobile to the
chart in your lab packet and calculate its speed. Remember, speed =
distance / time.
Based on your calculations, you will predict the order in which the
snowmobiles will finish the race. Be sure to record the calculated speeds
and your predictions in your lab packet! They will be lost when you
leave this page. If you run the program again, you will need to recalculate the speeds of the snowmobiles because each time you run the program the
results will be different. After running the race, record the order in
which the contestants finished.
Any time you see or hear the word per in the units for a value (miles
per hour, cows per field), you can think of it mathematically as
meaning divided by.
For instance, a
common way of measuring speed is in miles per
hour (mph) -- mathematically, this means
number of miles divided by number of hours.
If you drive 100 miles in 2 hours time, you are averaging
50 miles per hour.
- Now that you've "raced" the snowmobiles, was your
prediction about how they would finish right or wrong?
Try running the program again and recalculating the results -- everything
make sense? Piece-O-Cake.
