8.5mph equates to 13.7 (13.6794) kilometers per hour.
Nothing can travel faster than the speed of light which is 1080 million kms per hour. ( 300 x 106 metres per second)
Time = Distance/Speed = 100/140 = 0.714 hours = 43 minutes, approx.
1mile = 1.609 km Speed of light in kms-1 = 300000 kms-1 Speed of light in miles per sec = 300000/1.609 ms-1 = 186451.21 mps In mph, speed of light = 671224362.958 mph
If you ran 5 kms in 36 minutes, then your average speed is exactly 5 km per 36 minutes. Scaling it to a more familiar unit, it's also equal to 81/3 km per hour, and about 5.178 miles per hour.
about 90 to 95 kms
None. The speed limit is the limit. If you drive above it you are breaking the law. Simple, really.
at 60kmph you cover 60 km so at 10% of the speed you cover 6km. 10% of 60km is 6km and 10% of 60kmph is 6km. 6km= 1 hour at 6kmph or 10% of an hour at 60kmph or in time terms 6mins. the answer is 6mins.
Time = (distance) / (speed)Time = (400km) / (140 km/hr) = 2.857 hours = 2hrs 51min 25.7sec (rounded)
