Speed and velocity

Use the interactive calculator on page 80 of your text to check your work if you wish.

  1. Translate the following sentence into an equation.
    "The distance traveled is the speed multiplied by the time."
  1. How fast do you go if you move 80 meters in 0.20 seconds?
  1. A fox runs for 12 seconds at a speed of 9.65 m/s. How much distance does it cover?
  1. An object that starts at a position of 5m and travels for 3s at a velocity of -9m/s ends up at what position?
  1. The cheetah, the fastest land animal, can sprint at 30 m/s. Could the cheetah get a speeding ticket on a highway where the speed limit is 55 mph?
  1. How many minutes does it take to ride 5 miles on a bike going 15 mph?
