Two cars start from towns 630 mi apart and travel toward each other they meet after 6hr find the speed of each car one travels 25 mph than the other

We must think that the cars are traveling 630 miles in six hours.

Their combined speeds are x and x+25.

distance = velocity * time

Since, velocity = distance / time

(x + x + 25) = 630 / 6

2x + 25 = 105

2x = 80

So x = 40 mph and the other car's velocity is 65 mph.
