A man covers a distance on his scooter. If he had traveled 3 kmph faster he would have taken 40 minutes less. If he had traveled 2 kmph slower he would have taken 40 minutes more. Find the distance he traveled?
Internet solution:
Let r be the unknown rate and t the unknown time;
r*t = (r+3)(t-2/3)
r*t = (r-2)(t+2/3)
I then have to find r and t.
How do I find r and t?
I don't understand what I am actually solving?
If he traveled the same distance why can't I just, solve for a=b. But then I won't be able to solve the simultaneous equation?
I am not expecting a total solution just want an idea of what to solve......
