Question 936796: Two cars (X and Y) leave in the same direction. The car X leaves with a constant speed of 60 km/h and the car Y leaves with a constant speed of 90 km / h. For any distance D (in km) how long does it take (in minutes) for the car Y to reach this distance in relation to the other car.
You can put this solution on YOUR website! s = d/t
t = d/s
---
speed of car y relative to car x:
90 - 60 = 30 kph
---
t = D/30 hr * (60 minutes/hr)
---
answer:
t = 2*D minutes
