4 - (-1) = 5

 

-1 is not 1

Nope! The bus. It's already running anyway, and won't not run just because you don't ride it. However, you'll exhale more CO² if you ride you bike rather than the bus.
The wavelength of violet light is different than the wavelength of blue light, and due to the substances that make up our atmosphere, the violet light is let through, but some of the blue light is reflected off of the atmosphere back into our eyes.

Name one way that you can take 1 away from 4 and have 5 as your result.

This is complete bunk, a bus with you inside it will still emit more environment-harmful gasses than yourself riding on a bike. Your lungs cannot compare to the emissions of a diesel-fueled large vehicle.

I'm not sure if you're saying she's wrong or just translating it

sitting on the bus makes it weigh more, so it uses more gas

IDK about other cities, but in St. Louis the buses are powered by natural gas. :P

You're completely negating the fact that the bus is still running regardless of whether or not you're riding it.

The buses weigh many tons - it takes more than one person to change the amount of gas it uses considerably.

Agreed. Now, shutting down all the buses and having everyone ride bikes instead would be better.

one person is certainly enough weight for it to use enough extra fuel to compensate for not having to use your lungs as heavily

A man was in town and left on horseback on Monday. Six days later, he came back on a horse named Friday on Wednesday (a legit day). How is this possible?
