Waiting time for Vera = 35 minutes
Length of Vera's ride = 7 minutes
total processed time will; ( 35 + 7 ) = 42 minutes
the percent value-added time for this ride = ?

Percentage value-added time of Vera will be
= (length of the ride / total process time) × 100
we substitute
⇒ (7 / 42) × 100

Therefore the percent value-added time for this ride is 16.67%
