Explanation:
We have to travel 2000 km at a speed of 73 miles per hour. We have to find how long will it take us to go to Key West.
speed = 73 mi/hr
distance = 2000 km
Before we solve the problem we have to convert the km to mi.
1 mi = 1.61 km
distance = 2000 km * 1 mi/(1.61 km)
distance = 1242 mi
Finally we can find the time.
Time = 1242 mi * 1 hr/(73 mi)
Time = 17.0 hr
Answer: The trip will take 17.0 hours.
