The answer should be 299/52=almost 6 hours.
The answer is C because "dropped" means minus so it is asking: 2-5 which should be -3 not -5.
Okay so

= 75 minutes. Now we divide 40 by 75. 40÷75=0.53333333333333 miles. We know 1 hour is 60 minutes so we are going to multiply 0.5333333333333 by 60. 60×0.533333333333=32 miles. Therefore, your answer is 32 miles.
" always " is the wrong word....should be sometimes
usually the LCM is greater....
example : 2 and 4.....LCM = 8, GCF = 2
3 and 6....LCM = 12, GCF = 3
However, if ur 2 numbers are the same...
2 and 2.....LCM = 2 and GCF = 2
4 and 4....LCM = 4 and GCF = 4
