Question 428973: Rico can drive 2 times as far as oscar can ride his bike.If ir takes oscar 2 hours longer than rico to travel 20 miles, how fast can oscar ride his bike. Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! Let's take oscar's time as X. Rico can drive twice as fast, or 2X. Since rico arrives 2 hours earlier:
20/X =20/2X + 2
"""""=10/X + 2
Multiplying through by X we get:
20 = 10 + 2X
10 = 2X
5 = X
Oscar's speed is 5 mph. Rico's speed is 10 mph
