Usain bolt can run 150 meters in about 20 seconds if he could maintain this rate of speed how far can he run in kilometers in 1 hour

There are 3,600 seconds in an hour so just multiply 1500 by 3,600 and you get 540,000 meters. Then convert that into kilometers.

I think that is how you do it.

Distance=slopeslope is -2/4which equals-1/2the distance between these two points is -1/2

If there are four friends then each would get, 1.25 or 1 1/4. so this is how i solved 5 ÷ 4 = 1.25 . hope this ; )
