Question

ineedserioushelp · Answer

by 24d do you mean distance?

ineedserioushelp · Answer

like in the formula s = 24d, for speed equals 24 time distance?

anonymous · Answer

yes the question where the formula was Using the formula, square root 24d, find the speed of a car in miles per hour if it took 150 feet to stop. Round your answer to a whole number.

Well let's say a bicycle is going to the store, and it took him 150 feet until he got there, how fast was he going?

s = sqrt (24d)

s^2 = 24 * 150

s^2 = 3600	

s = 60

So, we used the formula to find out how fast he was going.

Yes. Thank you. I also wanted to know how to use the formula? How do I order the numbers in the expression and what do I do?

ineedserioushelp · Answer

Well the basic formula is:

s = square root (24d)

substitute d for the distance.

so let's say the distance is 150 like in your problem

we will use s^2 instead of s = square root

so, s^2 = 24 * 150

s^2 = 3600

√3600 = 60

so s = 60
