Answer:
(a) 0.6, 0.6, 0.65
Step-by-step explanation:
0.6 is equal to itself, so all instances of it can be grouped together in the list. Any positive decimal number is less than that same number with additional digits appended, so 0.6 < 0.65.
In this list of least-to-greatest, the values 0.6 will precede the value 0.65:
0.6, 0.6, 0.65

Answer:
3.6 hours
Step-by-step explanation:
To determine the time needed if they are working together, we use the formula
1/Ta + 1/Tb = 1 Tc
where Ta is the the time for the first item working alone
Tb is the time for the second item alone
Tc is the time for them working together
1/9 + 1/6 = 1/Tc
I multiply by 54Tc to clear the fractions
54Tc (1/9 + 1/6) = 1/Tc *54Tc
6Tc + 9 Tc = 54
Combine like terms
15Tc = 54
Divide each side by 15
15 Tc /15 = 54/15
Tc =3.6 hours
16 laps divided by 4 miles equals 4 miles, Therefore, 16 laps is equivalent to 4 miles.
