Problema Solution
You live 3.5 km from school. It takes you 30 minutes to walk to school. What is your average speed, in kilometers per hour?
Answer provided by our tutors
let
d = 3.5 km the distance
t = 30 min = 30/60 hr = 0.5 hr the time of the walk
v = the average speed
the formula for average speed is avg. speed = total distance/total time thus
v = d/t
v = 3.5/0.5
v = 7 km/hr
the average speed is 7 kilometers per hour.
