Problema Solution
On a train it took 3/4 hour to travel a distance of 52 1/2 miles. What is was the average speed of the train?
Answer provided by our tutors
Let
t = 3/4 hr = 0.75 hr the time of the travel
d = 52 1/2 mi = 52.5 mi the distance traveled
v = the average speed
v = d/t
v = 52.5/0.75
v = 70 mph
The average speed of the train was 70 mph.
