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
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.
If you travel 1 km in 1 minute, your speed is 60 km/h. This is because there are 60 minutes in an hour, so covering 1 km in 1 minute translates to 60 km in 60 minutes, which is 60 km/h.
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.
