Mayumi: 3 miles / 2 hours.
12 miles / 3 miles = 4
12 miles / 8 hours
Edwin: 4 miles / 3 hours.
12 miles / 4 miles = 3
12 miles / 9 hours.
Edwin takes more time to complete a 12-mile hiking trail. He takes 1 hour more than Mayumi.

Step-by-step explanation:
Answer:
a = 22
b = 7
Step-by-step explanation:
Let the two numbers be represented as a and b.
a + b = 29
a - b = 15
Using elimination method
Add both equations
2a = 44
Divide both sides by 2 to get a
2a/2 = 44/2
a = 22
Now substitute a = 22 in any of the equations to get b .
Using the first equation, we have
a + b = 29
22 + b = 29
Subtract 22 from both sides of the equation
22 - 22 + b = 29 - 22
b = 7
Therefore the two numbers are 22 and 7
