The figure suggests that the two sub-triangle are similar, because they are both right and the angle at the top is the same.
If that is the case, we can claim that the correspondent sides are in proportion:
Solving for x we have

multiply the number of hours by the number of minutes per hour
2.5×60=150
the answer is Aubrey played on the playground for 150 minutes
