If the hurricane averages 30 km/h over that 2100 km distance, you first find out how many hours it would take to cross 2100 km.
Therefore, you divide 2100 km by 30 km/h. This equals 70 hours.
Then you know there are 24 hours in a day, so you just divide 70 by 24 to figure out how many days. 70/24 = 2.9... ,so about 3 days.

Try to think of the problem in easier terms.
What if it had said: a person is walking at a speed of 2 miles per hour. How long would it take him to walk 10 miles?
one hour = 2 miles
two hours = 4 miles
three hours = 6 miles, and so on.
10 miles divided by 2 miles per hour = 5 hours
Do the same thing with the hurricane problem.
2100 km divided by 30 km per hour = ______ hours

Divide 2,100 km by 30 km/hr. Then divide the answer by 24 hr to convert it to days. The answer is C.

Take 2100 and divide by 30 and you get 70....so thats 70 hours...take the 70 hours and divide by 24(hours in a day) and you get 2.9 days...so about 3 days is the answer.
