Answer:
- Jenny 1.75 miles, Keith 4.75 miles, Jonna 9.5 miles
Step-by-step explanation:
<u>Distance per person:</u>
- Jenny - x, Keith - y, Joanna - z
<u>Equation as per given:</u>
- y = x + 3
- z = 2y = 2(x + 3)
- x + y + z = 16
<u>Substitute and solve for x:</u>
- x + (x + 3) + 2(x + 3) = 16
- 2x + 3 + 2x + 6 = 16
- 4x = 7
- x = 7/4 = 1.75
Then
- y = 1.75 + 3 = 4.75
- z = 4.75*2 = 9.5
