Answer:4
Step-by-step explanation: each quarter of an hour is 1.5 miles they both can go into 12 so if you multiply 2*4 and 3*4 you get 8/12 and if you multiply 3*3 and 4*3 you get 9/12 then you subtract 9/12 by 8/12 to get so 1/12=1/2 miles so you would subtract 4 1/2 by 1/2 to get 4
(7/10 + 1/2) * 5/8 -1/2
parenthesis first....common denominator is 10
(7/10 + 5/10) * 5/8 - 1/2
12/10 * 5/8 - 1/2...reduce when u can
6/5 * 5/8 - 1/2
now we multiply
30/40 - 1/2
3/4 - 1/2
now we subtract...common denominator is 4
3/4 - 2/4 = 1/4 <== ur answer
