well if 6 is half of 12 im sure 60 is half of 120 so A
(x-2) + (x-1) + x + (x+1) + (x-2) + (x+3) = 447
6x + 3 = 447
6x = 447 - 3
6x = 444
x = 444/6
x = 74
Answer:
65.837 km/h to nearest thousandth
Step-by-step explanation:
60 ft/s = 60 * 3600
= 216,000 ft /h
1 foot = 30.48 cms so
216,000 ft/h = 216,000 * 30.48
= 6583680 cms / h
= 6583680 / 100,000
= 65.837 km/h to nearest thousandth
