First you divide 39/40
you would get 0.975
3 because 7*3=21,...........
-3y +4 = -11
-4 -4
-3y = -15
—— —-
-3y -3y
Y= 5
Let x = amount of time the Arlen family must catch up to
overtake the Harris family
In principle, the Harris and the Arlen family should cover
the same distance. Since distance is speed x time,
45 (6+y) = 58y
270 + 45y = 58y
58y - 45y = 270
y = 270 ÷ 13
y= 20.77min
Answer:
m = 2
