Problema Solution
An airplane flew 264mph to Airport B and flew back to Airport A in 462mph in 7 hours. What is the distance between Airport A and B?
Answer provided by our tutors
let 't' represent the time in hours it took to fly from Airport A to Airport B, then '7-t' represents the time it took to fly from Airport B to Airport A
distance = speed * time
the distance was the same, so we set the speed * time expressions equal to each other
264t = 462(7-t)
solving for 't' we have t=4.45
264 mph for 4.45 hours is a distance of:
264 * 4.45 = 1174.8
the distance from Airport A to Airport B is approximately 1175 miles
