Two frogs have a race.  One frog makes a jump of 80 cm once every 5 seconds.  The other frog makes a jump of 15 cm every 1 second.  The rules of the race state that the frog must cross a line 5 meters away and then come back to the starting point.  Which frog wins the race?  Can you determine by how much?

 

 

 

 

Extension: Come up with 3 ways you could you change the rules of the race to have a different winner? (You cannot change the frogs’ jumping abilities.)
