Herman is traveling 125 miles from his house to the beach by car. Herman plans to stop for lunch when the ratio of the distance
aliya0001 [1]

Answer:

250 miles

Step-by-step explanation:

The given distance between the house and the beach is 125 miles.

Let x miles be the distance between the house and the lunch stop.

So, at the time of the lunch stop, he already traveled x miles, the remaining distance is the distance between the lunch stop and the beach.

Let y miles be the remaining distance, so

y=125-x.

Give that the ratio of the distance he has traveled, x, to the distance he still has to travel, y, is 2:3,i.e

x:y=2:3

\Rightarrow \frac x y =\frac 2 3

\Rightarrow \frac {x}{125-x}=\frac 2 3

\Rightarrow 3\times x=2\times(125-x)

\Rightarrow 3\times x=2\times125-2\timesx

\Rightarrow 3 x=250-2x

\Rightarrow 3x-2x=250

\Rightarrow x=250

Hence, the distance traveled by Herman when he stops for lunch is 250 miles.
