Mr. Khalifa is driving a boat at top speed, 15 km across open water.

His motorboat can travel at a top speed of 45 km/h. If he has already
driven the boat 3 km, how long will it take for him to get to his destination?

Rest distance=15-3=12km

  • Speed=45km/h


\\ \sf\longmapsto Speed=(Distance)/(Time)


\\ \sf\longmapsto Time=(Distance)/(Speed)


\\ \sf\longmapsto Time=(12)/(45)


\\ \sf\longmapsto Time=0.266h\approx 0.27h
