Question

So If Mr. Cohen drives 84 2/10 miles on Tuesday,84 6/10 miles on Wednesday,85 miles on Thursday how many miles would He drive on Sunday

Answer 1

I think that he would drive 86 7/10 miles because it goes up by 4/10 miles each day

Answer 2

Because the miles Mr. Cohen drives increase by $\frac{2}{5}$ on each day, so Mr. Cohen will drive $85 + \frac{2}{5}$ × 3 = 86$\frac{1}{5}$ on Sunday
