Math question I can't figure out

[ThePresence]

Let's say New York and Philadelphia are 100 miles apart. A car leaves New York travelling 50 MPH. towards Philadelphia. A car leaves Philadelphia travelling towards New York at 40 MPH. They both leave at 12:00 noon. What time do they pass each other on the highway?

Maybe I'm dumb. My nephew asked me this one and I feel like a fool for not knowing. I don't think it's a trick question.

Traffic is not an issue. 🙂

pretty easy but involves thinking and thats where you lose me

v=d/t

d=tv

100=tv

100=50t+40t

90t=100
t=100/90
t=10/9=1.11111 hours after they left.

(Time)*50+(Time)*40=100

You figure it out now.

what kind of cars?

I think the price of gas has something to do with this...

Amazingly Google maps says they're 100.2 miles apart 😕

The question states that the cars leave New York and Philadelphia but nothing
says they don't turn off along the way and "take the scenic route" so maybe
they didn't even pass each other?

I think this is called "thinking outside the box".

Are the drivers talking on their cell phones?

What kind of cars are they driving? What are the chances that one or both cars will suffer a mechanical failure?
What are the chances of driver error?

Foreign - 0.4%
American 12.3%

You didn't specify the sex of driver for the last question, so it cannot be answered.

Are the drivers getting road head?

It is also called evading the question.
