Question 706099
A student traveled 219 km in 14 days.  At the same ratio, how far would a student travel in 28 days?


Let the distance travelled in 28 days be x.

Therefore:

14 : 219

28 : x

Cross Multiplication:

14 * x = 14x

219 * 28 = 6132


14x = 6132

Divide each side by 14

14x/14 = 6132/14

x = 438


Therefore in 28 days the student will travel 438 km.
