How do you find the constant speed of an object given distance and time?

Justin has no food in the house, and decides to take his Segway to the local drive through, hoping that being on a Segway counts as 'driving'. How fast does he need to go in order to cover the 2 mile distance in 15 minutes?

Summary

  1. H- Justin's home
  2. D- The drivethrough
  3. d- Distance
  4. s- Scooter speed
  5. t- Time of travel
  6. Problem Solved!

Notes

    1. Constant speed means that you don't get faster, and you don't get slower
    2. Think d=s•t when you see constant speed
    1. d- distance
    2. s- speed
    3. t- time
    4. Think of this with constant speed problems
    1. d- distance
    2. s- speed
    3. t- time
    4. Here we've solved for speed
    1. t- time
    1. s- speed
    2. mph- miles per hour
    1. s- speed
    2. mph- miles per hour
    3. Our final answer is that speed is 8 miles per hour
    1. t- time
    2. s- solved speed of 8 mph
    3. A- area
    4. Problem solved!
    1. The area under a speed vs time graph tells you the distance travelled
    1. Area of a rectangle is base times height, or 0.25 hrs times s miles per hour
    1. s- speed
    2. mph- miles per hour
    3. Our final answer is that speed is 8 miles per hour
