The overall trip is 15 min for the 6 miles. Plugging that into the equation for Average velocity you get 6m/15min. The answer is asking for m/h. So we know there are 60 minutes in 1 hour. You cross multiply 6m/15min with 60min/1h and get 360m/15h and can reduce it to 24m/h.

Answer:
B. Bubonic plagues
Explanation:
Bubonic plague is caused by Yersinia pestis. Rats, prairie dogs and squirrels are the pests that harbour the disease while fleas serve as vector, carrying the Yersinia pestis to humans.
The human victim either touches a dead infected rodent or is bitten by an infected flea. The bacteria invade the skin and are gobbled up by macrophages. They continue to reproduce intercellularly and within lymph nodes especially the inguinal nodes. The nodes swell like eggs and become hot, red and painful. Fever and headache sets in. Hemorrhages under the skin cause a blackish discoloration leading people to call bubonic plague the "Black Death."
Without treatment, death occurs within a few days. Treatment is with antibiotics such as streptomycin, doxycycline.
Answer:Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply. ... In response to infection, your immune system springs into action. White blood cells, antibodies, and other mechanisms go to work to rid your body of the foreign invader.
Explanation:The main job of the innate immune system is to fight harmful substances and germs that enter the body, for instance through the skin or digestive system. The adaptive (specific) immune system makes antibodies and uses them to specifically fight certain germs that the body has previously come into contact with.
