You can put this solution on YOUR website!
the speed of the first car is 320/4 = 80 kmph.
the speed of the second caris 375/5 = 75 kmph.

the ratio of the speed of the first car to the second car would be 80/75.
simplify to get 16/15.

the ratio of the speed of the second car to the first car would be 75/80.
simplify to get 15/16.

the first car travels 16/15 times as fast as the second car.

the second car travels 15/16 times as fast as the first car.

let f represents the speed of the first car.
let s represent the speed of the second car.

f/s = 16/15

solve for f to get f = 16/15 * s.

s/f = 15/16

solve for s to get s = 15/16 * f.
