I will assume these are times and both are AM on the same day

4:24 to 9:24    is   5 hours 0 minutes difference

Use the starting point and midpoint to calculate the slope and the distance, then extend the distance twice as far.    If you give your specific example we can help you....

Without more info than what you have given, there are infinite 'solutions'.

Nothing unusual here....

example     4x  *  1/3   =  4x/3

                   4x *  2/5   =   8x/5

First , calculate the sqrt(99) = 9.95

pi^2 = pi x pi = 3.14 x 3.14 = 9.87

    and you are given              9.8

SO the smallest is   9.8    the next greater is  9.87  (pi squared)   and the greatest is 9.95

....or you can just factor it:

35-b^2 = 2b          add  'b^2 - 35 ' to both sides

0=b^2 + 2b - 35

(b+7)(b-5) = 0        Now either  b+7   or  b-5  (or both) = 0   so b = -7 or 5

THAT is a REALLY big subject......do you have something specific to ask ?

No, the cashier gave him back too much money in change....she gave him 12.30

12.30 + 38.70 = 51   not 50 dollars     she should have given him a 10 dollar bill ONE one dollar bill and 3 dimes for 11.30

First, convert  88.2 km/hr to m/s

88.2 km/hr x 1 hr/3600 s  x 1000m/1km = 24.5 m/s

Then vf = vo + at     vf= 0 (car comes to a stop)  vo = 24.5     a = -300m/s^2

0 = 24.5 + (-300)t    yields t = .081667 s

xf=xo + vot + 1/2 at^2

xf =  24.5 (.081667) + 1/2(-300)(.081667)^2      yields  xf = 1.00 m    (minumum barrier thickness)
