The tumbling run by Alena lasted for 0.009 seconds.

The time of tumbling can be calculated using the formula -

time = (2 × theta) ÷ (initial angular velocity + final angular velocity)

Keep the values in formula to find the amount of time took while tumbling.

Time = (2 × 0.5) ÷ (43 + 65)

Performing multiplication in numerator and addition in denominator of Right Hand Side of the equation

Time = 1 ÷ 108

Performing division on Right Hand Side of the equation

Time = 0.009 seconds

Thus, Alena took 0.009 seconds in tumbling while performing floor routine.
