Tanker A moves at 18 mi/h and Tanker B moves at 22 mi/h. Both are traveling from Corpus Christi, Texas, to St. Petersburg, Florida, 900 mi directly east. Simulate the tanker movements if Tanker A leaves Corpus Christi at noon and Tanker B leaves at 5 P.M.
a. Write parametric equations to simulate the motions.
b. Name a graphing window and a range of t-values that show this situation.
c. When and where does Tanker B pass Tanker A?
d. Simulate the tanker movements if both tankers leave at noon, but Tanker A leaves from Corpus Christi and Tanker B leaves from St. Petersburg, each heading toward the other. Record your equations and determine the time interval during which they are within 50 mi of each other.
