How do you calculate travel time from distance and speed?

Travel time (t) equals distance (d) divided by velocity (v): t = d / v. For example, traveling 500 kilometers at an average speed of 100 km/h requires 500 / 100 = 5.0 hours (300 minutes).

How fast does internet data travel through fiber optic cables?

Light moves through vacuum at ~300,000 km/s, but in silica glass fiber with a refractive index of ~1.47, light travels at approximately 204,000 km/s (126,800 miles/sec). Crossing a 4,000 km continent takes roughly 19.6 milliseconds of one-way transit time.

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (meter per second (m/s)) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 vs (water) = 1482.008418 meter per second (m/s)

2. Target SI Bridge (k_target):1 kn (UK) = 0.514773 meter per second (m/s)

Step-by-step substitution for Velocity of sound in pure water → Knot (UK):V(kn (UK)) = V(vs (water)) × ( 1482.008418 / 0.514773 ) = V(vs (water)) × 2878.95336
