30 mph, as a mile is longer than a kilometer.
After 1 hour the slower car will be 30 mph x 1 hour = 30 miles ahead of the faster car. The faster car is travelling 45 mph - 30 mph = 15 mph faster than the slower car and so will cover this 30 miles in 30 miles ÷ 15 mph = 2 hours at which point it will have caught the slower car and start to over take it.
30 km/hour = 18.6 MPH.
30 km/h = 18.64 mph
30 meters per second is faster than 1 mile per minute. 30 meters per second is about 67.1 mph. A mile per minute is 60 mph.
