Velocity = Distance ÷ Time : therefore Time = Distance ÷ Velocity.
Let the distance travelled at 40mph be 'x' miles, then the distance travelled at 60mph is 410 - x.
Then 7 = x/40 + (410 - x)/60 : which leads to 20x = 16800 - 16400 : x = 20
Thus Sam travels 20 miles at 40mph (taking 1/2 hour) and 390 miles at 60mph (taking 61/2 hours).
