Light travels 300,000 km per second, or 300 million meters/second. Convert the 2 hours to seconds, then multiply by 300 million.
15.3 km = 15 300 mTo convert from km to m, multiply by 1000.
Rate = distance / time : so (300 km)/(4 hr) = 75 km/hr
300 minutes
72.3 km = 72 300 mTo convert from km to m, multiply by 1000.

The average speed of the car = 300 [km] / 5.5 [h] = 54.55 [km/h]. ==========================
300km in 3 hours = 100km per hour
You cannot. 300 km is a measure of distance while mph is a measure of speed.
To convert kilometers per hour (km/h) to miles per hour (mph), you can multiply the km/h value by 0.621. Thus, 300 km/h is approximately 186.4 mph.
You obviously need to know how long the period of travel is in hours, then multiply by the speed.
It's not possible; km is a measure of distance, hours is a measure of time. These units measure completely different things, hence are not convertable. (In the same way that you cannot convert inches into years etc...).
