A cyclist travels 17 km from home to the park.
She leaves home at 17:15 and arrives at the park at 17:45.
What is her average speed in km/h?

Respuesta :

Answer:

34 km/h

Step-by-step explanation:

speed = distance/time

Distance = 17km

Time = 0.5 or 1/2 hours because it's 30 minutes between 17:15 to 17:45, and 30 minutes is a half of an hour and you want km over hours

So

speed = 17/0.5

speed = 34 km/h
