time = (4,700 kilometers) / (790 kilometer per hour) = 5.9494 hours. Don't try this at home until you know how to figure in the effects of the wind.
Suppose you traveled 180 miles in 4 hours. The unit rate would tell you how miles you'd travel in just one hour. So 𝘶𝘯𝘪𝘵 means 1. And you'd divide the total 180 miles by 4 hours to get your answer. One mile per hour = ________.Let's say Jackie bought a 5 pound bag of potatoes for $15. The unit rate would tell you how much each 1 pound bag would cost. One bag = $______ per pound.
10, or 100. The decimal system would make many calculations much simpler. Of course, the hour would also have to be divided into decimal minutes (10 or 100), and each minute in decimal seconds (10 or 100). Or simply indicate fractions of a day, such as "I'll see you in 10 milli-days" (about a quarter hour, according to the current system).
