Type a nerve fibers in humans can conduct nerve impulses at speeds up to 140 m/s. (a) how fast are the nerve impulses in miles per hour? 313.17 correct: your answer is correct. mi/h (b) how far (in meters) can the impulses travel in 3.1 ms?

a. 313.171081 miles/hour
b. 0.434m

To calculate the speed in miles per hour, you need to change meterinto miles (1m= 0.086992mile) , then second into hour(1s= 1/3600h). The calculation would be:
140 m/s x 0.086992mile/m : 1/3600 s/hour= 313.171081 miles/hour.

To calculate the next question you need to know that mili second= 1/1000 second. Then the calculation would be:
140m/s x 3.1ms x 1/1000= 0.434m

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2
