TEST YOUR SKILLS IF A DRIVER WAS ABLE TO TRAVEL 600 KM IN 3 HOURS, WHAT WAS HIS AVERAGE SPEED? SPEED = DISTANCE/TIME SPEED = 600 KM/3 HOURS SPEED = 200 KM/HOUR (200 KPH) THE FASTEST CAR ON EARTH, THE BRITISH-MADE THRUST SSC, CAN TRAVEL 380 MILES IN 0.5 HOURS. WHAT IS ITS SPEED? SPEED = DISTANCE/TIME (S=D/T) SPEED = 380 MILES/0.5 HOURS SPEED = 760 MILES/HOUR (760 MPH)
