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?

Respuesta :

Rest distance=15-3=12km

  • Speed=45km/h

[tex]\\ \sf\longmapsto Speed=\dfrac{Distance}{Time}[/tex]

[tex]\\ \sf\longmapsto Time=\dfrac{Distance}{Speed}[/tex]

[tex]\\ \sf\longmapsto Time=\dfrac{12}{45}[/tex]

[tex]\\ \sf\longmapsto Time=0.266h\approx 0.27h[/tex]
