Runner #1 is 35m ahead of Runner #2.
Runner #1 travels at 1.65m/s and Runner #2 travels at 1.85m/s.
Both run in the same direction.
From where they begin, how far does Runner #2 travel before he catches up with Runner #1, how long does it take?
I know i have to use variables, but i'm lost. Any help please
You don't have to use any equation or formula for this question. We will just use our imagination :)
(This solution is similar to my post here)
First, imagine the scene as you're on the ground, standing, looking at the runners. You see that they're 35 m away and running at the same direction at 1.85 m/s and 1.65 m/s.
Now, imagine the scene as you are Runner #2. You're 35 m behind Runner #1. You both start running. Ignore the grounds. What do you see? You see that Runner #1 gets closer at 0.2 m/s! (it's 1.85 - 1.65). We just calculated the relative speeds. And now, he's 35 m ahead and coming closer at 0.2 m/s. When would you meet? It's so easy,
Now you work the rest :)
I really have to remember this way of solving, test in 2 hours so
