Answer:
-10
Step-by-step explanation:
If the equation is 2 x 3+4 x 2-3 x 2- 6(x)= . Than the equation would turn into 2 x 3+4 x 2-3 x 2- 6(3) which equals -10.
Distance = rate * time (I will abbreviate as d = rt)
d = rt, so r = d/t
r = 20mi/24min
= 0.833333 mi/min.
d = rt again for the new time
d = 0.8333333 mi/min * 6 min = 5 miles
Just a little conversion (I recommend writing it out, so you can see the terms cancel out):
39 feet/minute x 1 yard/3 feet x 1 minute/60 seconds= .21667 yards per second
