shut off the engine, wait for all moving parts to
stop, remove key, and engage parking brake.
7. Average the 3 test run times (in seconds);
use the average course time formula.
Record the average course speed here:
Average Course Time Formula
(time 1) + (time
Formula 2) + (time 3)
Example 21.6 + 19.1+
18.4 seconds
8. Calculate the average ground speed; use the
ground speed formula. Record the average
ground speed here:
Note:
1 kph = 16.6 m/minute (1 mph = 88
ft/minute)
Ground Speed Formula
Course length
Formula m (ft) x 60 seconds
Course time (seconds) x
16.7 m/minute (88 ft/minute)
Example 45.7 m (150 ft) x 60 seconds
19.7 seconds x 16.6 m/minute
(88 ft/minute)
