Problema Solution
On a road trip from Buffalo, New York to St. Augustine, Florida a family wants to travel at least 250 mi in the first 5h of driving. What should the average speed be in order to meet this goal?
Answer provided by our tutors
the average speed = the total distance/the time of the travel
v = d/t
in our case d = 250 mi and t = 5 hr. we plug these values in the above equation:
v = 250/5
v = 50 mph
the average speed in order to meet the goal is 50 mph.
