Question

A freight trains departs from one train station to its destination at a constant speed. Suppose the distance the train is from the station in miles in represented as a function of the number of hours after the train departed from the train station. If the graph of the function passes through the points (0.5,135) and (2,81), what is the distance between the train station and the freight train’s station?
153 miles
189 miles
171 miles
162 miles

Answer 1

Answer:

Distance = 54 miles (Approx)

Step-by-step explanation:

Given:

Co-ordinate of two point = (0.5,135) and (2,81)

Find:

Distance

Computation:

Distance = √(x1-x2)²+(y1-y2)²

Distance = √(2-0.5)²+(81-135)²

Distance = √2.25 + 2916

Distance = 54 miles (Approx)
