What is average speed?
The average speed of an object in motion is obtained by dividing the total distance traveled by the object with the time spent in the entire journey.
v = total distance/total time
where;
- total distance = 144 miles
- total time = from 6:30am to 6:30pm = 12 hours
v = 144/12
v = 12 mph
Thus, the average speed of the sailboat is determined as 12 miles per hours.
