There is 1 mile for 1.6 Kilometers so 20km/1.6=12.5miles So 20km is further than 12 miles
45km/h because you add the two speeds together and divide. so 50+40=90/2 = 45
An African Lemur's top speed is 20km/h (12mph)
Average speed = Distance/Time = 20/5.17 = 3.87 km per minute.
If you divide the distance by the time, you'll get the average speed. In this case, the answer will be in km/hour.
20km over the speed limit will incurr immediate loss of license
20km is 12.4274 miles.
30km/h = 30km/60min = 5km/10min 20km/h = 20km/60min = 10km/30min 5+10=15km
Distance = (speed) x (time)Time = (distance) / (speed)= 1 / 20 hour = 3 minutes
Type your answer here... yes it is a 20km marathon
