A plane is 300 miles west of city A and is flying west at 400 miles per hours. How long will it take for the plane to be 1800 miles west of city A

Answer 1

The plane is 300 miles west of city A. You need to go 1500 more miles to get to 1800 miles west of city A. The plane is flying 400 mph.
So, 400x= 1500. 400 being speed, x being hours, and 1500 being miles.
so, you get 3.75 hours. You need to change the .75 hours into minutes, so .75 or 3/4 of an hour is 45 minutes. 3 hours 45 minutes.
Beware with these type of questions, sometimes you have to change the hours to minutes or yard or feet to inches before you start,
Hope this helps, good luck.
