Match the Speed to Its Equivalent

3 pts

volume_mute

To complete the line match

Click on an item in the first group
Click on an item in the second group
To delete a match, double click on a line

Given Speed

60.0 mi/h

67.3 km/h

52.09 km/h

Equivalent

14.47 m/s

96.1 km/h

18.7 m/s

Match each speed on the left with its correct converted value on the right. Where needed, use 1.602 km = 1.000 mi.
