Question

The speed of nerve impulse is about ___ times slower than speed of electricity.

• A. $1.5\times {10}^5$ meters per second
• B. $1.5\times {10}^6$ meters per second
• C. $1.5\times {10}^8$ meters per second
• D. $1\times {10}^2$ meters per second

Answer 1

The correct option is B

$1.5\times {10}^6$ meters per second

Speed of electricity is 150000 Km per second. That converts to $1.5\times {10}^8$ meters per second. Speed of neuron is 100 meters per second and hence, the relative speed is about $1.5\times {10}^6$ meters per second.
