If you mean 253 km/h, then: 1mi = 1.61km 253km/h x 1mi/1.61km = 157mi/h
205.05mph if you mean km/h
Answer: 162 mph = 260.713 km/h
If one's speed changes from 10 km/h to 6 km/h, one has decelerated.
93V meam tyre safety speed is up to 150M/h or 241 km/h.
It changes more from 20 km/h to 30km/h. -Answer from Penn State University Physics 001 Homework
547.16 km h
under the assumption you mean Km/h the answer is 180 Km
207 mph = 333.134208 km/h
By kmh you probably mean km/h. If so, (40-35)km/h=(45-40)km/h=(50-45)km/h=5km/h is the change in velocity each second and (5km/h)= (5km/h)(1h/3600s)=0.0013888889km/s=(0.00138km/s)(1000m/km)=about 1.38m/s and the acceleration is the change in velocity divided by the change in time. The acceleration is then a=(1.38m/s)/1s=about 1.38m/s2.
307.4 km/h
