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.
