At 7:00am, Claire leaves the spa, driving her car at 80kph she reaches her house at 7:15am, packs her artwork, and at 7:45am, leaves for the design lab, which is 10km from her house. If she drives her car at 40kph in going to the design lab, what will her average speed be from the spa to the lab ?
O 30 kph
O 40 kph
O 53.3 kph
O 60 kph
O 66.7 kph

My Doubt :- Do we have to include half hour stop time to calculate average spped. If yes then the answer is correct.
