Question

Represent the situation in the form of quadratic equations.
Q. A train travels a distance of480 km at a uniform speed had been 8 km/h less,then it would have taken 3hrs more to cover the same distance. We need to find the speed of the train

Answer 1

Answer:

let uniform speed be x km/hr.

initial time = 480/x

new time = 480/x-8

as per the given condition,

480/x + 3 = 480/x-8

480/x-8 - 480/x = 3

480x -480x + 3840 /x² - 8x = 3

x² - 8x - 1280

factorize and u will get the answer
