MATH HELP!!! Word Problems!?

Question

NUMBER 1) Cory and Keith are cousins who live exactly 36 miles apart. The boys decide to meet halfway between their houses. At the same time, they start riding their bikes toward each other. Each boy is riding 6 miles per hour.
Keith has adog that starts running the instant that Keith starts biking. The dog runs back and forth at 18 miles per hour between the two cousins houses until the cousins meet. How far does the dog travel???

NUMBER 2) Kyle, Gladys, and Robert are cousins. ALl three cousins have different heights. Kyle is 14 inches taller than Gladys. The difference between Kyle and Robert is 2 inches less than the difference between Robert and Gladys. At 6'6", Kyle is the tallest. How tall are Robert and Gladys???

Answer 1

1)Each boy will travel 18 miles. It will take the boys 3 hours to make this trip at 6 miles per hour. In three hours the dog will travel 18miles/hour x 3 hours = 54 miles

2) The three equations are:

K - 14 = G
K - R + 2 = R - G
K = 6'6" or 78"

Solving the three equations:
G = 78 - 14
G= 64" or 5'4"

78 - R + 2 = R - 64
2R = 80 + 64
2R = 144"
R = 72" or 6'

Answer 2

S=1/2 *36=18km
the dog Travel =2*18km=36km Back and Forth


Kyle=6'6"=195
Gladys=195 cm-35 cm=160cm 0r 5'4"
The different between Kyle and Gladys is 14 "
K-R=R-G*2
K+G=2R+2"
6"6" +5'4"-2"=2R
11'8" hence Robert Height= 6'2"

Answer 3

cory---------------------36 miles-----------------------Keith
@6 miles each travel 36/2=18 miles which is 18/6 miles per hour the meet after three hours.
cousins meet after 3 hours ie
--------------------------------------------------------------dog@18 miles
dog speed is 18 hours so it can distance boys travel is 18 miles so dog runs twice to meet them up and down
