Time and Distance question

[Flelm]

It's right, but could be done without the line stuff.

distance = time * velocity

Car A: x = t * 51
Car B: x - 1 = t * 50

(Car B travels 1 mile less in the same amount of time)

Two variables, two equations. You can do a number of solving methods, but I'll just substitute.

(t*51) - 1 = t*50
t-1 = 0
t = 1

Time is 1 hour.

To find the distance, use t in either of the above equations.

x = t * 51
x = 1 * 51
x = 51

51 Miles.
