The speed of a nerve impulse in the human body is about 100 m/s. if you accidentally stub your toe in the dark, estimate the time it takes the nerve impulse to travel to your brain

We can estimate it like this: In the case of the nerve impulse, this one would reach your brain in about 1 second Because since it goes 100 meters per second then it will take only thar time. If You were a little less than 50 times shorter, so the nerve impulse must take a little less than 1/50th of a second. If you need to do this calculation again you can use the following formula: distance traveled = speed of travel * time it takes. If this is true so 
time = distance/speed. I hope this can help you

Mars and earth have quite a few things in common. both are  terrestrial planets, both are located within the sun’s  habitable zone, both have  polar ice caps, similarly  tilted axes, and similar  variations in temperature. and according to some of the latest scientific data obtained by rovers and atmospheric probes, it is now known that mars once had a  dense atmosphere  and was covered with  warm, flowing water.
