Jimmy has a choice between two remote-control cars, a 1967 Ford Mustang and a 1976 Ford Pinto. He would like to have the faster one, but the models are manufactured in different countries and thus have a different maximum speed printed in the specifications.

What is known:

  • The maximum speed of the remote-control 1967 Mustang model is 29 ft/s.
  • The maximum speed of the remote-control 1976 Pinto model is 10 m/s.
   
  Question

 

What is the maximum speed of the 1967 Mustang and the 1976 Pinto remote-control model in both mi/hr (mph) and km/hr? Which car is faster?

     
    Approach

   
  • Convert the speed of both cars to a common set of units, mph and km/hr, and then compare the speeds.
