average rate of speed = total distance traveled / time traveled
total distance traveled = 51 miles
time traveled = 9 hours
average rate of speed = 51 miles / 9 hours
= 5.67 mph
hence the average rate of speed taken by a ship to cross from one end of a canal to the other end which is 51 miles at a time of 9 hours is approximately
5.67 mph.
moving at this speed indicates that the ship is running on a very low speed because if it were to be a car, the car would cover that same distance at a faster time.
<span>1) 51 divided by 9= 5.6 miles per hour 2) I'm not sure about this one, but I think it's because at the ends, you are still in the Atlantic or Pacific ocean until you get farther into the Panama Canal.</span>
