Rate  *  Time = Distance

w = walking rate

b = biking rate = w +8

(w+8) * 25/60   = distance    (25/60 is the amount of hours    25 min = 25/60 hours)

w   *  1.25        = distance

(w+8) * 25/60 =  w * 1.25

25/60 w   +  8 * 25/60   = 1.25 w

3 1/3   = 1.25 w - 25/60 w

            = .8333w

w = 3 1/3  / .8333 = 4  km /hr         = walking speed

rate x time = distance

4 km/hr * 1.25  hr =   5 km   = distance between house and repair shop

a = age

1/2 a + 3  = 1/4 a + 7

1/4 a = 4

a = 16

4 dresses x  3 shoes = 12 choices

to BOTH be non white there are 3 dresses x 2 shoes = 6 choices       6 out of 12     6/12     1/2

Almond is  3  out of   3+5 +7 =15 parts

3/15  x  = 9kg

x  = 9 * 15/3 = 45 lbs of cereal

Her rate   is 12 n / 2 hr = 6 necklaces/hr

9 necklaces / 6 necklaces/hr =  9/6 = 1 1/2 hr

5/6 min for first lap

second lap   5/6 x 13/12

third lap        9/10  (5/6 x 13/12) = 585 / 720   minute =585/720 =   13/16 min

2^4  3^4    would work......

2 x 3 x 3 x 5 x 11         2+11 = 13

7 is to 8     as   x is to 10

7/8 = x/10

x = 7/8 * 10= 70/8 = 8 3/4 cm

What exactly does an  a(b/c) button do?     a*b/c  ?
