9 (c - 6) = 63
9c - 54 = 63
9c = 117
c = 13
Hmm try 192.5 I think that’s right
If you drive 53 miles per hour, you will have traveled 159 miles in a span of 3 hours
Assuming both Mario and Todd just walked today.
Mario is every 8 days
Todd is every 14 days.
The days that will coincide is the Least Common Multiple (LCM) of 8 and 14
2 / 8 14
2 / 4 7
2 / 2 7
7 / 1 7
/ 1 1
The LCM = 2 * 2* 2* 7 = 56
The will both walk together in the next 56 days.
