Donnie, Karim, and Shawn run on the cross-country team. Donnie ran twice as far as Karim. The ratio of the distance that Karim ran to the distance Shawn ran is 4: 3.

If you add the distance that all three boys ran, you get 45 miles. How far did each boy run individually?

then i tested out multipling each of the numbers in the ratio by different numbers at a time, and doubled the highest one (Karim's), then added them to see if they made 45.

Ex. 4:3

4(2):3(2) = 8:6

double 8 = 16

8+6+16= 30 aka not the answer, try something else.

4(3):3(3) = 12:9

double 12 = 24

12+9+24= 45 , meaning Karim is 12 and Shawn is 9 because their ration is 4:3, and Donnie is 24 because he ran twice as far as Karim.

Donnie, Karim, and Shawn run on the cross-country team. Donnie ran twice as far as Karim. The ratio of the distance that Karim ran to the distance Shawn ran is 4: 3. If you add the distance that all three boys ran, you get 45 miles. How far did each boy run individually?
