Question

Charles drove three times as far as Emily. Altogether they drove 112 miles. What was the number of miles driven by Charles?

Answer 1

Charles drove 84 miles.

Answer 2

Answer: Charles drove 84 miles

Explanation:

(c)harles = 3 x (e)mily

e + c = 112

Since Charles is 3x Emily, we can plug in 3e instead of c

e + 3e = 112

4e = 112

e = 112/4

e = 28

Emily drove 28 miles, and Charles drove 3x that, so Charles drove

28 x 3 = 84
