I think its -2x since 4x/2=2x and then 8x/2=4x so they subtract both answers = -2x also if you subtract 4x-8x=-2x. Sooo it might be 2x just saying

An airplane takes off 12.5 miles south of a city and flies due north at a constant speed of 170 miles per hour. What is the plan
atroni [7]

Answer:

Option B

Step-by-step explanation:

Speed is distance moved per unit tine and is expressed as s=d/t

Making d the subject then

d=st

Where d is distance, s is speed and t is time taken in time.

Conversion

1 hour has 60 minutes hence 45 mins converted to hours will be 45/60=0.75

Substituting 0.75 hours for t and 170 mph for s then

d=0.75*170=127.5 miles due North

However, tge plane had initially moved 12.5 miles hence the relative distance due North will be 127.5-12.5=115 miles due North
