Step-by-step explanation:
2/3 minutes = 2/3 min * 60 sec/min = 40 sec
5 ft/sec * 40 sec = 800 ft
X=12 because 73-3x=61-2x so add 3x to both to make 73=61+X then subtract 61 from both to get 12=X
Remember that X will always be one up or down depending on if there is a - or not (if it is just an x) and one over! Hope this helps
