At exactly 2: 00 pm, speedy the hermit crab crawl onto a meter stick starting at the 10 cm mark. if he reaches the 60 cm mark at exactly 2: 10 pm, what is his speed?

speed=5cm/minute

Explanation:

Given at 2:00PM the hermit is at 10cm mark

Also given that the hermit reaches 60cm mark at 2:10PM

Therefore the time elapsed is  10 minutes =

the distance travelled by the hermit is 60-10=50cm=0.5m

We know that

speed = m/sec=5cm/minute

sry but any answer choices

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
