A hot-air balloon, headed due east at an average speed of 15 mph and at a constant altitude of 100 feet, passes over an intersection. Find an expression for its distance d (in feet) from the intersection t seconds later.
Do I use D = rt?
If so, then D = 100 feet, right?
Then r = 15 mph, right?
100 = 15(t)
100/15 = t
Am I right or wrong?
If wrong, what did I do wrong?
I thank you for going the extra mile with this question.
I don't think the question asked for an answer but it's good to know that an expression and answer were displayed by you here.
