4 km in 30 min, or
4 km in 0.5 hr
So that the average speed is 8 km/hr.
547
Its speed is 120 kilometers per hour.
30 km/h
540 kilometres per hour.
The speed is the distance traveled divided by the time it takes to travel that distance. In this case we with divide 8 kilometers by 10 minutes to get 0.8 km/minute. One hour is sixty minutes, so this works out to 48 km/hour.
Hint: There are 60 minutes in an hour...
55 minutes is 55/60 hours. 6km divided by 55/60 = 6.5km/h
8 kph
6 kilometers per hour
You need speed to calculate this. Distance is speed / time
45 minutes in ¾ of an hour, so just divide 15 kilometers by ¾ hours and get 20 kilometers per hour.
Need average speed to calculate.
60 kph
In order to calculate how many minutes it would take someone to travel 5 kilometers you need to know the speed the person is traveling at. For example if the person is traveling at a speed of 60 kilometers an hour it would take them 5 minutes to travel 5 kilometers.
With the information given, it's not possible to calculate what it is now. But during that 90 minutes, its average velocity was 50 kph north.
4 kilometers
3km/12min = 0.25km/min
14.4 km per hours
