Jack completed 3/5 of his two-day trip in the first day. how much longer was the first day of his trip than the second day, if the whole trip was 350 miles long?

Work Shown:

3/5 of 350 = (3/5)*350 = 0.6*350 = 210

Jack travels 210 miles on day 1

On day 2, he travels the remaining 350-210 = 140 miles

Subtract the values 210 and 140 to get 210-140 = 70

One other way to get this answer is to break 350 miles into 5 parts

350/5 = 70

Each part is 70 miles

Three of those parts is for the first day, so 3*70 = 210 is how much he travels on day 1.

The other two parts are for the second day, so 2*70 = 140 is the amount he travels on day 2.

We do the same subtraction as before: 210-140 = 70 to figure how how much further he goes on day 1 compared to day 2.
