Answer 2

Answer: 245 m

Step-by-step explanation:

36= 120m, 72h

42= y,126h

36= 120/72

= 1.66666666667

42= y/126

= x

36:1.66666666667::42:x

Product of extremes= product of means

36 * x = 1.66666666667 * 42

X = 1.66666666667*42/36

X = 1.94444444444

y/126 = x

y/126 = 1.94444444444

y = 1.94444444444*126

y = 245 meters
