In Scientific Notation. 112 kilometers per hour. = 1.12 x 10 2 kilometers per hour. ≈ 6.95936 x 10 1 miles per hour. We can also convert by utilizing the inverse value of the conversion factor. In this case 1 meter per second is equal to 0.035999999999971 × 100 kilometers per hour. Another way is saying that 100 kilometers per hour is equal to 1 ÷ 0.035999999999971 meters per second . The first 50 km it travels 30 km/h and the second 50 km it travels at 60 km/h. Its average speed would be distance /(time interval) = (100 km)/[(50 km)/(30 km/h) + (50 km)/(60 km/h)] = 40 km/h. If the car had spent equal times at 30 km and 60 km rather than equal distances at these speeds, its average speed would have been 45 km/h. Kilometers per second Kilometers per second to Kilometers per hour formula Kilometers per hour. This is a measurement of speed typically used in countries using the metric system for transport. Road speed limits are given in kilometers per hour which is abbreviated as kph or km/h. In Scientific Notation. 145 kilometers per hour. = 1.45 x 10 2 kilometers per hour. ≈ 9.00988 x 10 1 miles per hour. In Scientific Notation. 185 kilometers per hour. = 1.85 x 10 2 kilometers per hour. ≈ 1.14954 x 10 2 miles per hour.
