6km = 6000m 6000m/35s = 171.43 m/s 3600s=1h 35s / 3600 s/h ~= 0.00972 h 6km / 0.00972 ~= 617 km/h
Average speed is 6km/3hr = 2km/hr = 2KPH.
There the same 6000m-6km 6km-6000m
90 kmh
If one's speed changes from 10 km/h to 6 km/h, one has decelerated.
6km = 6000m 6000m/35s = 171.43 m/s 3600s=1h 35s / 3600 s/h ~= 0.00972 h 6km / 0.00972 ~= 617 km/h
About 6km/h.
The impact speed is 100 - 98 = 2 kmh.
one MPH is 1.6 KMH, you do the math.
110 kmh = 68.3508 miles per hour.
59 mph
kmh is itself a unit. Kilometer per hour is the unit of speed and velocity.
About 6km/h.
88.8kmh
34 kmh
(60 + 40) ÷ 2 = 50 kmh
140 kmh
