Problema Solution
An eagle can fly at a speed of 50mph and a starling can fly at 78mph. How far will the starling fly in the time it takes an eagle to fly 125 miles?
Answer provided by our tutors
Let
v1 = 50 mph the speed of the eagle
v2 = 78 mph the speed of the starling
d = 125 mi the distance that the eagle flew
t = the time of the eagle
Since speed = distance/time follows time = distance/speed thus
t = d/v1
t = 125/50
t = 2.5 hr
Next we use the formula distance = speed*time and we find the distance of the starling s:
s = v2*t
s = 28*2.5
s = 70 mi
The starling will fly 70 miles.
