Jabari's average speed exceed the speed limit by 17 miles per hour

Given:

Total distance = 20.4 miles

Time taken = 17 minutes

convert minutes to hour

60 minutes = 1 hour

17 minutes = 0.283333 hour

Average speed = Total distance ÷ Time taken

= 20.4 ÷ 0.283333

= 72.00008470598200

Approximately, 72 miles per hour

Speed limit = 55 miles per hour

Exceeded speed limit = 72 - 55

= 17 miles per hour

Therefore, Jabari's average speed exceed the speed limit by 17 miles per hour

How do you simplify algebraic expressions?  
masya89 [10]
There are many reasons one may want to simplify, rearranging to find specific values - or maybe just making it simpler
Well, let's do some examples:
y(x(3+2)) +2 = -2y +2   <span>< I just made this one up, it looks really complicated right now, none the less it can be simplified easily
</span>y(3x+2x) + 2 = - 2y +2
3xy + 2xy + 2 = -2y +2
5xy + 2 = -2y +2    <-- the +2's dissapear because they cancel out
5xy = -2y

<span>And there we have it, that long expression has been simplified to something really simple.
</span>
Another example:
3(4(x+3(2 +z)) - 5)= 3y <span><- you can start where ever, I like starting in the middle
</span>3  *  (4 *  (x +  3*(2 + z)) -  5 ) = 3y  <span><-  here it is spaced out, we get a much better view
</span><span>3  *  (4 *  (x +  6 + 3z) -  5 ) = 3y</span>
3  * (4x + 24 + 12z - 5) = 3y <- divide both sides by 3 ..
4x + 24 + 12z - 5 = y <- much better
<span>
</span>Note: Simplify means solving to a degree, but you can't solve it because it has unknowns
