Nerve impulses travel at different speeds, depending on the type of fiber through which they move. In a scenario, the impulses for touch traveled at 75.0 m/s, while those registering for pain moved at 0.84 m/s. If a person stubs his toe, find the time delay between the pain and touch impulses. Assume that his brain is 1.51 m from his toe and that the impulse travels directly from toe to brain. Express your answer in seconds.   Hint: Always take the positive value. Time difference is synonymous to time delay
