Question 556697: You decide to drive across the country to visit your aunt in California. The number of miles (m) you travel each day varies directly with the number of hours (h) you drive that day. On the first day, you drive for 9 hours and cover 405 miles.
Write the direct variation equation expressing miles in terms of hours. Use the letters m, k, and h only.

We have m = kh where k is a constant (in this case, velocity). Since 405 = 9k, we obtain k = 45. Hence, m = 45h.
