Answer: 4
Step-by-step explanation:
There's 6 hours and twenty minutes between 8:20 and 2:40, which means you would divide 335 mi by 6.2 hrs. Thats gets you the answer of 54 mph (54.03 to be exact.) Hope that helps!
First note that the nth root of a number, a, is a^(1/n).
So you have:
(x^5)^(1/8)
Next note that (a^b)^c=a^(bc) so you have:
x^(5(1/8))
x^(5/8) or if you'd rather have a decimal...
x^(0.625)
I believe the answer would be true.
