Jimmy can run 3.5 miles in 20 minutes. How far can he run in one hour and ten minutes?
Dmitry [639]

Answer:

12.25 miles

Step-by-step explanation:

We can write a proportion to solve.  Miles over time in minutes

1 hour = 60 minutes

1 hours 10 minutes = 60+10 = 70 minutes

3.5 miles         x miles

---------------   = --------------

20 minutes         70 minutes

Using cross products

3.5 *70 = 20x

245 = 20x

Divide each side by 20

245/20 = 20x/20

12.25 =x

Jimmy can go 12.25 miles

How do I solve this equation?
Gnom [1K]

2x(4-x)^{-1/2}-3(4-x)^{1/2}=(4-x)^{-1/2}\bigg(2x-3(4-x)\bigg)

We effectively rewrite the equation as

\dfrac{5x-12}{(4-x)^{1/2}}=0

In order for the LHS to be defined, we need to restrict 4-x>0, or x. Now, the LHS will vanish when the numerator is 0, which happens for

5x-12=0\implies5x=12\implies x=\dfrac{12}5

This value is indeed smaller than 4, so the solution is x=\dfrac{12}5.
