D=RT (Distance = Rate x Time)

[color=#FF0000]Heres is the math problem:[/color]

If a parade 2 mi long is proceeding at 3 mph, how long will it take a runner, jogging at 6 mph, to travel from the end of the parade to the start of the parade?

[color=#FF0000]The book said the answer is 2/3 hr.

Would the equation look like this:

6n - 3n = 2

If this is the correct way, can you make sense of it for me because I can't.[/color]

Re: D=RT (Distance = Rate x Time)

Yeah, that formula look good.

Think of it as the jogger running the same distance as the parade plus the 2 miles for the length of the parade.







The jogger travels however far the parade travels plus the length of the parade. See now?.

The jogger's rate relative to the parade is 6mph - 3mph, i.e., 3mph,
so time = distance / rate = 2 miles / 3 mph = 2/3 hr.
