Problema Solution
It takes a hospital dietician 30 min to drive from home to the hospital, a distance of 24 mi. What is the dietician's average rate of speed?
Answer provided by our tutors
The formula for the average speed is:
average rate of speed = the distance traveled / the time of the travel
v = d/t
In our case the distance traveled is d = 24 miles while the time is t = 30 min = 30/60 hr = 0.5 hr.
We plug the values into the equation v = d/t and find the average speed:
v = 24/0.5
v = 48 mph
The dietician's average rate of speed is 48 mph.
