Start with the speeds of the cars:
 Car A can travel at 110 mp/h.
Car B can travel at a speed of (110 x 0.9) 99 mp/h.
Car C can travel at a speed of (110 + 99)/2 = 104.5 mp/h.
If it took car A 30 minutes, the length towards the middle of the triangle is 55 miles.
Calculate how long it takes car B and car C travel 55 miles:
Car B → It will take her (55/99) hours which is 33 minutes and a third.
Car C → It will take her (55/104.5) hours which is approximately 31.6 minutes.
Therefore the differences in the time will be approximately 1.5 minutes.
