Answer:
30 feet
Step-by-step explanation:
Interesting question.
- 1 cubit = 18 inches
- 20 cubits = x
- 1/20 = 18/x Cross multiply
- x = 20 * 18
- x = 360 inches.
The maximum height is 360 inches.
- 1 foot = 12 inches
- x feet = 360 inches Cross multiply
- 12x = 360 * 1
- 12x/12 = 360/12
- x = 30
The maximum height reached was 30 feet.
Substitute the 1st equation in the 2nd, we get:
3x + 2(-3 + 2x) = 2
3x -6 +4x = 2
7x = 8
x = 8/7
Replace x = 8/7 in equation 1,
y = -3 + 2(8/7) = -3 +16/7 = -5/7
