Answer:
175/3 or 58.333...
Step-by-step explanation:
This is fairly complicated but I will try to make it as simple as possible. I also apologize in advance for how impossible it is to make fractions look like fractions. I also had to insert a bunch of unnecessary parentheses just because the fractions that I can make are relatively inaccurate.
The distance between 2 cities can be represented as d.
Time is d/r if r is rate, so B->NY=d/50
Similarly,NY->B is d/70
Obviously the average speed is 2d/(d/50+d/70), this is just an average time
Now just remove the d and get (d/d)*2/(1/50+1/70)
You can now multiply by the LCM/LCM, which is 350/350.
After calculating you will get 700/12 which is 58.333...(This is how to enter into your RSM browser) Hope this helps. Sorry it is so late.
Umm 8/12 or 2/3 .......................................................................
The answer is 2√3
I hope this answers your question :)
6 ones 7 hundredths -2.3
We make a place chart for 6 ones 7 hundredths. We write 0 in the remaining place value.
Hundred tens Ones point tenths hundredths thousandths
0 0 6 . 0 7 0
6 one 7 hundredths is 6.07
Now subtract 2.3 from 6.07
6.07 - 2.3 = 3.77
Answer : 3.77
