Distance cannot be expressed in time. If it could, then you'd be able to figure out how many minutes high your house is, and how many miles of sleep you had last night.
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...).
