we have that
step 1
Find the unit rate
Allie
Divide 5 1/2 by 1/4
remember that
5 1/2=5+1/2=11/2
so
(11/2)/(1/4)=22 meters per hour
Samuel
Divide 14 1/4 by 3/4
14 1/4=14+1/4=57/4
(57/4)/(3/4)=19 meters per hour
Part A
Verify each statement
1) we have 22 meters per hour,
so
1 m------> 1/22 hour
the first statement is true
2) we have that
Samuel -----> 19 meters per hour
second statement is false
3) 19 meters per hour
third statement isTRue
4) Allie clims at 22 meters per hour
fouth statement is true
Part B
we have that
after the first hour
Allie------> 22 meters
Samuel ---> 19 meters
For another 1/2 hour
Allie-------> 22+11=33 meters
Samuel need to climb (33-19)=14 meters in 1/2 hour
so the rate is
14/(1/2)=28 meters per hour
