Speed=distance/time
average speed=(total distance)/(total time)
total distance=203+243=446
total time=3.5+4.5=8
average speed=(446)/(8)=55.75
answer is A
Isolate the x
divide 3 from both sides
3x/3 > 6/3
x > 6/3
x > 2 is your answer
Note: because you are not dividing by a negative number, you do not need to flip the sign
hope this helps
