Question 1124025
Plane B is flying 55mph faster than Plane A. Find the time it takes for Plane A to travel 1800 miles if it takes Plane B the same amount of time to travel 1965 miles.
<pre>Let T be the time taken by both
Then we get the following SPEED equation: {{{matrix(1,3, "1,800"/T, "=", "1,965"/T - 55)}}}
1,800 = 1,965 - 55T -------- Multiplying by LCD, T
1,800 - 1,965 = - 55T
- 165 = - 55T
T, or time taken by both = {{{highlight_green(matrix(1,4, (- 165)/(- 55), "=", 3, hours))}}}
That's all!! Nothing complex!!
