I really do not know the answer to this question
Answer:
the answer is 66.205
Step-by-step explanation:
basically you look at the place value so
66.21 is basically the same as 66.210 then you look at the lowest number that can round UP to 66.210 which would be out of 1 to 9 would be 5 so the smallest number that can round up to 66.210 is 66.205 hope this helped :D
Step-by-step explanation:
a 12 miles per hour * 45/60 = 9 miles
b I mean he can't ride negative speed, unless he's going backwards??
-8 * 45/60 = -6 miles
c they would be abs(-6) + 9 = 15 miles apart
Since there is no decimal point, the answer is 345276.
Time taken to drive to her grandparents house = 6 5/6 hours
We convert this mixed into improper fraction, we get = 41/6 hours
Time taken to drive to her grandparents house = 41/6 hours
Time taken to drive back = 8 2/9 hours
We convert this mixed into improper fraction, we get = 74/9 hours
Time taken to drive back = 74/9 hours
Difference between the two = 74/9 - 41/6 = (148-123)/18 = 25/18 hours = 1 7/18 hours
Therefore it took 1 7/18 hours longer to drive back.
