Question
On April 18, 1775, Paul Revere set off on his midnight ride from Charlestown to Lexington. If he had ridden straight to Lexington without stopping, he would have traveled 11 miles in 26 minutes. In such a ride, what would the average speed of his horse have been, to the nearest tenth of a mile per hour?
The correct answer is: 25.4
speed = distance / time
distance = 11 miles
time = 26 minutes
Since the speed is needed in miles per hour, we convert 26 minutes to hour by dividing 26 by 60. That is, 26/60 = 13/30 hours
Thus,
speed = 11 / (13/30)
= 25.4 (in nearest tenth)
