Answer:
1. 126 kph(kilometers per hour)
2. 504 kilometers in four hours.
Step-by-step explanation:
For #1, the formula for converting from meters per seconds is 3.6m = k, when m is the speed is meters per seconds, and k is the speed in kilometers per hour.
For #2, simply multiply the kilometers traveled in 1 hour(as already defined) by 4.
Hope this helps!
