Question

Kansas City and Denver are 600 mi

apart. Two cars start from these cities.
traveling toward each other. They meet
after 6 hr. Find the rate of each car if one
travels 30 mph slower than the other.

Answer 1

65 mph; 35 mph

Explanation:

let x = rate of car 1

x-30 = rate of car 2

distance = rate x time

6x = 600 - 6(x-30)

6x = 600 - 6x + 180

6x = 780 - 6x

12x = 780

x = 780/12 = 65 mph

x - 30 = 65 - 30 = 35 mph
