Well if you divide 49 by 3 people you would get a decimal number then you round up
A= there are "4"one fourths in one hour and he hikes 2 miles every hour
B= 1, 1 1/2, 2, 4
C= it going to be 1/3 mile for every 1/6hour and she hikes 2 miles every hour.
D= 2/3, 1, 2, 4
Your answer is
1,000,000,000 (one billion)
Hope this helps.
