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

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)

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
