Mike rides his motorcycle at an average speed of 20 meters/ seconds for 500 secs, how far did he ride?
You can do this by arranging the numbers with a simple method.
20 m / 1 sec = x m / 500 sec
You can now cross multiply (multiply each numerator by the other fraction's denominator).
20 * 500 = 10,000
1 * x = x
x = 10,000
This means that in 500 seconds, Mike can ride his motorcycle 10,000 meters!
That's a really fast motorcycle, in my opinion!

P.S. Sorry if I misunderstood the question. I think you made a typo and forgot to type how many seconds it takes for Mike to ride 20 m!
