16x+4=110+3x+11
13x=117
x=9
1/2 turns into 2/4 and 2/4 + 1/4 that equals 3/4 and then 11 plus 6 equals 17 3/4
we know that
speed = (total distance)/(total time)
so, total distance =60+180+540+660
total distance =1440 mi
total time =10+30+90+110
total time =240 min
now, we can change time into hours
total time =
total time =4 hours
now, we can find speed
speed of the plane in miles per hour is 360 mph...........Answer
(-9k+8k)*-1
