An ambulance was invented that could travel at the same speed as a helicopter. If an ambulance left Vidaliia at the exact same moment as the helicopter, which one would reach Savannah first, and why?

• The helicopter would reach Savannah first because it only had to travel the displacement velocity.

• The helicopter would reach Savannah faster, because the helicopter is capable of traveling faster than an ambulance.

• The ambulance would get there faster than the helicopter because it has a siren and could travel full speed through any intersection.

• The ambulance would get there faster because it does not have as many people traveling in it.
