Burn the first one for 45 minutes then light the second one. They won't finish burning simultaniously, but you haven't specified that in your question.
The train is running 4 minutes late. It "needs" to be running 1/2 hours, or 30 minutes late. So it needs to lose 26 minutes, or 26*60 = 1560 seconds. It loses 4 seconds per minute. So it loses 1560 seconds in 1560/4 = 390 minutes = 61/2 hours.
None. Minutes is a unit of time. Miles is a unit of measurement. The only way you get miles per hour is by knowing the speed of travel. This question needs work to get an answer.

She needs to leave at 6:45 am. It is not possible to draw a number line here.
The female mosquito needs the blood to produce eggs.
Light both coils one one end at the same time and let them burn for 30 minutes. At 30 minutes, light the other end of both coils (so that the coil is burning from both ends [inner and outer tip]).Rationale: If it takes 1 hour (60 minutes) to burn the entire coil, then it takes 30 minutes to burn 1/2 of the entire coil. After 30 minutes, 1/2 the coil remains to be burned. After both ends are lit, the coils are burning twice as fast and will only require 1/2 the amount of time (1/2 of 30 is 15) to burn the remaining coil as did the already burned section of the coil.So: 30 min + 15 min = 45 minutesThe problem with the above solution is how do you know when 30 mins has elapsed?So here is my solution: light one coil at both ends and the other coil at one end. The first coil with burn twice as fast and be consumed in 30 mins. When that happens, light the other end of the second coil also. The second coil's remaining half will burn in 15mins. Problem solved!
To develop eggs to lay an animal needs to eat food. The food of a mosquito is blood, thus blood is required before the female mosquito can lay eggs.
Because they need blood to survive like Vampires!! And you have blood inside you. Only the female mosquito bites. This is because she needs the extra nourishment contained in blood for her eggs to be viable.
Every mosquito can bite and pierce human skin. When feeding on human blood, mosquitoes pierce the skin and trigger histamines in the body.
it needs to contain the chemical DEET to be effective.
A symbiotic relationship implies that both species need each other to survive and benefit each other in different ways. A mosquito eats from a man or animal, and man needs the mosquito to maintain ecosystem balance as one of the lower members of the food chain.
A mosquito typically bites multiple times before it dies, as it needs to feed on blood to survive and reproduce. The exact number of bites can vary depending on factors such as the mosquito species, its age, and environmental conditions.
Because HIV needs human immune cells to reproduce and does not survive in an insect.

Nothing. The motor is not doing work. A voltage needs to be switched between the coils for it to go.
