Jackie is going to be the fastest woman in the world, marion jones. marion can run 9.5m/s while jackie can only run 7m/s. for obvious reasons, jackie will get a headstart of 40m. how long should the race be so that jackie barely wins?

wait if jackie can run 7 m/s then she already is the fastest

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
