Okay after sleepinng on it I see what it is I did wrong. I was supposed to divide 91/29 to get 3.137...rounded gives me 3.14 so then I divide the 5/3.14=1.6 and that's my answer. I solved it but I am still confused. I was assuming that 29s was my speed. It is actually my time? what is it...

okay this just sounds like energy being conserved to me ...no?

:rolleyes: No there isn't... that was the question on the study sheet I assumed this mean that it was never really lost it was just converted into a different type of energy. In my textbook it says that energy can not be destroyed but can be converted??

In 1977 Steve Weldon ate 91m of spaghetti in 29s. At the same speed how long would it take Mr. Weldon to eat 5m? Okay, I believe they are asking for the time...so the formula would be Time= d/V so what I did was divide the 5m by 29 and that does not make sense do I have to convert the...

There is nothing else in this question just that.

I got this question on a study sheet however, I am not sure if I understand, I thought that there was no such thing as a lost of energy because it can not be destroyed. However it can convert into a different type of enery. Please help me get a clue.:rolleyes:

duh!I can't believe it! 0.5 exponet 3 is 500 I see that I do have a problem with the math more than anything because I am trying to convert the 500 into minutes but I am still lost. I know . Okay 500/60 is 8.3 right because there are 60s in a minute:rolleyes: I can't believe It took me...

it is 0.5 right?

I know what the formula is however, when I apply it I do not get the same answer that is in the book the The answer is 500s=8.3min is inthe answer key at the back pf my book... Okay so I need to handle exponents separate. okay, I am getting 50exponent3 because when you divide exponents you...

The speed of light is 3.0 x 10 exponent8 m/s. How Many minutes does it take for light to reach the Earth from the sun. Which is 1.5 x 10 exponent11 m away? I know the formula is t=d/v so ?=1.5 x 10 exponent11 m /3.0 x 10 exponent8 m/s The answer is 500s=8.3min...I just don't know how...
