Question

Rico can drive 3 times as fast as Pablo can ride his bike. If it takes Pablo 3 hours longer then Rico to travel 36 miles,how fast can Pablo ride his bicycle?

Answer 1

Answer:

Pablo rides his bicycle at 8MPH

Step-by-step explanation:

So, we can make this into a equation

Remember, D=S*T

So we create this type of equation:(If it is a bit complicated, sorry)

$\frac{36}{x} - \frac{36}{3x}=3$

What I am doing here is that I am using D/S=T, But in a formula that accounts for both of them.

So, Let's Solve!

$\frac{108}{3x} -\frac{36}{3x} =3\\\frac{72}{3x} =3\\72=9x\\8=x$

Sorry, If it doesn't make sense... :(

Anyways, Have a Great Day! Hope This Helps!

P.S. Stay Safe!
