Question

If John takes 45 minutes to bicycle a total of four kilometers northwest to his grandmothers house , what is the velocity in km/hr?

Answer 1

time = 45 minutes

distance = 4 kilometers

direction = Northwest

Since the velocity is in km/hr, convert minutes to hours:

1 hour = 60 minutes

45 / 60 = 0.75

45 min = 0.75 hours

Velocity = distance / time = 4 km/ 0.75 h = 5.33 km/ h , northwest.
