Aparachutist's speed during a free fall reaches
198
feet per second. what is this speed in meters per second? at this speed, how many meters will the parachutist fall during
5
seconds of free fall? in your computations, assume that
1
meter is equal to
3.3
feet. do not round your answers.

"Dimensional analysis" is the primary way to make conversions between any units.  Some have trouble because they fail to make it an important point to label units, but labeling units correctly makes tracking and making any conversion very simple...The process and thinking is that you want to cancel out units that you don't need in the solutions...

(198ft/s)(12in/ft)(2.54cm/in)(m/100cm)=60.3504m/s  (and that is exact)

d=5s(60.3504m/s)=301.752m

ugh...assume that a meter equals 3.3 feet and do not round your answers???
really?  These people are idiots when there is an exact conversion.  What is the point of not rounding when you are using a horrible approximation?  :D

(198ft/s)(m/3.3ft)=60m/s

d=5s(60m/s)=300m

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8

It's like discovering the answer to a puzzle. the purpose in solving an equation is to find the value or values of the variable that makes it a true statement. any value of the variable that makes the equation true is called a solution to the equation.
