Answer:
240kmh
Step-by-step explanation:
The distance that the train traveled in 30s is the difference of the total length of the tunnel and the train (2000m). This means it travels 2000m/30s. This ratio is the same as 240000/3600s or 240km/1hr.
Si = prt
Si = 1260 (0.03) (2)
Si= 1260 (0.06)
Si = 75.60.
So it’s 1260 + 75.60 = $ 1335.60
Answer:
10(32 - n)
Step-by-step explanation:
This is a beginning algebra question. It is trying to find out if you know what a difference is.
A difference always means subtract in math. Always. There are no exceptions.
So the difference between 32 and n is 32 - n
This difference is multiplied by 10
10(32 - n)
Usually the number mentioned first is the number put to the left of the subtract sign.
If you tell me the answer is 10(n - 32) then you should say that it is the difference between n and 32.
