Asalesman drives from ajax to barrington, a distance of 150 mi, at a steady speed. he then increases his speed by 10 mi/h to drive the 182 mi from barrington to collins. if the second leg of his trip took 2 min more time than the first leg, how fast was he driving between ajax and barrington?
the 48 boys is 4 parts of the ratio
divide 48 by 4 to obtain one part of the ratio
= 12 ← 1 part of the ratio
3 parts = 3 × 12 = 36 ← number of girls
ok then what happened.
