If you travel 10 km in 45 mins how fast are you going?
You are traveling 0.22km per minute or you need 4.5 minutes to travel one km
What is your average velocity if you drive a distance of 232 km at a speed of 46 km per h then the same distance at a speed of 70 km per h Answer in units of km per h?
This kind of question is tricky, because average velocity is not simply the average OF the velocities. The reason is you spend more time driving the slower part. The correct approach is to compute (average velocity) = (total distance) / (total time) Total distance = 232 + 232 km. Total time = (time going 46 km/h) + (time going 70 km/h) The above terms are found by computing distance/speed: at 46 km/h, it takes (232 km) / (46 km/h) = (232/46) hours etc. - you can finish the details.
In km per hour find 2.4 km in 30 mins?
4.8 km/h
How may klms an hour to run 8 mins miles?
1 mile ≈ 1.61 km 60 mins = 1 hour ⇒ 1 mile per 8 mins = 1 mile ÷ 8 mins ≈ (1 x 1.61 km) ÷ ((8 ÷ 60) hours) ≈ 1.61 x 60 ÷ 8 km/h ≈ 12.1 km/h
How many km are in 10 dkm?
1dkm = 10 km 10 dkm = 100 km
