Problema Solution
Two airplanes are leaving O'Hare at the same time..one bound for New York and the other for California. The one heading to California has a tail wind and is going 25 mph faster than the one headed to New York. If after one hour they are 575 miles apart, what are their speeds?
Answer provided by our tutors
Let C. N be the speeds of airplanes headed to California, Newyork .
C=25+N.
In one hours distance covered by airplane headed to California =C miles.
In one hours distance covered by airplane headed to Newyork =25+N miles.
C+25+N=575.
C+N=575.
C-N=25.
By adding
2C=600.
C=600/2 =300 mph.
N=575-300=275. mph.
