122.5 kilometres per hour!
The speed of sound of the harrier is the same as the speed of sound of any other object in the relevant medium. It is approx 1225 km/hour.
80 km per hour
60 km/h
Average speed = distance/time = 200km/4 hours = 50 km per hour
6 km/h
The speed of sound of the harrier is the same as the speed of sound of any other object in the relevant medium. It is approx 1225 km/hour.
The speed in km/hour must be given. The answer is obtained by dividing 250 km by speed in km/hour
80 km per hour
It is 60km per hour.
If you meant 25 km/hour then the horse will travel 12.5 km in 30 min.(1/2 hour) .
Distance does not affect the average speed. A car can travel 1 kilometre at an average speed of 60 km per hour, or it can travel 100 km at the same average speed.
30 km
Speed doesn't travel. Light travels.Light goes about 300,000 km in a second; in an hour, it goes 3600 times as far, since an hour has 3600 seconds.
Around 500 km/hr
60 km/h
That depends on the speed. The circumference of the Earth is 40,000 km. Decide on a speed, then divide this distance by the speed. If the speed is in km/hour, the time will be in hours.
You obviously need to know how long the period of travel is in hours, then multiply by the speed.
