Question

The Speed Of A Freight Train Is 14 Km Slower Than The Speed Of A Passenger Train The Freight Train Travels 330 Km In The Same Time That It Takes The Passenger Train To Travel 400 Km Find The Speed Of The Freight Trian

Answer 1

Freight train DATA:

rate = x-14 kmh; distance = 330 km ;time = d/r = 330/(x-14) hrs

------

Passenger Train DATA:

rate = x km/h ; distance 400 km ; time = d/r = 400/x hrs

-----

Equation:

time = time

330/(x-14) = 400/x

-----

330x = 400x - 14*400

70x = 14*400

x = 80 km/h (speed of the passenger train)

---

x-14 = 66 km/h (speed of the freight train)
