Many of the immigrants settled on farm land and they had to drive to town for supplies. One farmer drives to town at 36 miles per hour and returns at 48 miles per hour. If his total driving time is 3 ½ hours, how far is his farm from town?

t + (36/48)t = 3.5hrs.
t + 0.75t = 3.5,
1.75t = 3.5,
t = 2hrs = Time to reach town.
0.75t = 1.5hrs = Time to return home.
d = v*t = 36 * 2 = 72 Miles.
Or d = 48 * 1.5 = 72 Miles.
