Jack and jim went biking. jack biked for 5 1/3 hours with average speed 12 1/2 miles per hour. jim traveled exactly 1 1/5 as far as jack did. how long was jim’s trip?

jim traveled 80 miles

Step-by-step explanation:

how far did jack travel

d =rt

d = 12 1/2 miles per hour * 5 1/3 hours

change to improper fractions

12 1/2 = (2*12 + 1 /)  2 = 25/2

5 1/3 = (3*5+1) /3  = 16/3

d = 25/2 * 16/3 = 25/3 * 16/2 = 25/3 *8 =200/3 miles

jim traveled 1 1/5 times as far

change this to an improper fraction

1 1/5 =  (5*1+1) /5 = 6/5

jim = jack * 6/5

jim = 200/3 * 6/5

     200/5 * 6/3

      40 * 2

     80

jim traveled 80 miles
