11Second formula, cos it involves no approximation.
But didn't we study that the first formula was an approximation of the second?
I don't think 64≈32!
33Formula..
as 1st one is approximation for the second formula so as long as both formulas give nearly same answers u can use both but as soon as they show difference use the basic one.. second one..
12nd formula should be applied and answer should be 64 kms. but answer given is 32 kms... ??? may be wrong!
