The time, T seconds it takes a water heater to boil a constant mass of water is inversely proportional to the power, P watts, of the water heater.

When P=1400, T=360

Find the value of T when P=900

I get a huge number of T=453600000 - i'm sure i'm using the correct method and therefore this should be the correct answer- just checking to see if you guys get the same answer!

Thanks

I have the equation v(t) = 5t mph, [t is in seconds] and I have to find the total distance in miles in its accelaration. And the car accelerates from 0 to 25 mph.. I think the seconds conversion is messing with my brain.


oh and I posted this by accident in the History section... oops. I fail

Just wondering do you think the level of difficulty will be about the same in November's paper - as i'm doing it for my retake and am hoping to find it about the same? Also as the majority of GCSE students take the exam in June how do you think the grade boundaries will be affected?

My daughter and I just got a large box of assorted seashells at a yard sale. We would like to know the correct names. We have a few books and have found a few of the shells in them but there are many more. They are not local shells. Is there anyplace online where we might get some help? I know there must be thousands of different kinds of seashells and no site will picture them all, but any help will be appreciated.
