Question

An airplane takes off 12 and a half miles south of a city and flies due north at a constant speed of 180 miles per hour what is the plane's position relative to the city after 45 minutes

Answer 1

1. 180×.75=135
2. 135-12.5=122.5
3. the answer 122.5 miles north of the city

Answer 2

so a plane takes off 12.5 miles south of a city and flies north at 180 mph
in 45 mins how far is it away from the city
|(x)| means absolute value of x
so |(12.5-(180/1 times x-hours))|=distance
1 hour=60 mins
45=3/4 of 60
the plane flew 3/4 hour
180 times 3/4=540/4=135 miles traveled
|(12.5-135)|=122.5 miles away from the city
