Calculate the average speed in km h of a car that drives 140 kilometers in two hours?
Marjeeee
if u want speed do distance divide by time but first u need to change 120 km to meters and 2 hours to minutes then divide them
* * * * *
Why change km to metres and hours to minutes? Why not just do 120 km / 2 hours = 120/2 km per hour = 60 km per hour. The end!

∙ 12y agoLet us change 70.0 m/s to kph
70.0 m/s (1 kilometer/1000 meters)(3600 seconds/1 hour)
= 252 kilometer an hour
Distance = Rate * Time
Distance = 252 Kph * 6.5 hours
= 1638 Kilometers

Total distance = (112 + 182) = 294 km
Total time = (112/79 + 182/100) = 3.2377 hours (rounded).
Average speed = (294 / 3.2377) = 90.805 km/hr(rounded)
