Two trucks leave a warehouse at the same time. one travels due north at an average speed of 62 miles per hour, and the other travels due south at an average speed of 61 miles per hour. after how many hours will the two trucks be 676.5 miles apart?

let H = hours

62H + 61H = 676.5

123H = 676.5

676.5/123 = 5.5

H= 5.5 hours
