Best Answer

One kilometre is equal to 1000 x 1000 = 1000000 millimetres. Therefore, 180 kilometres per second is equal to 180 x 1000000 = 180000000 millimetres per second.

There are 3600 seconds in one hour. Therefore, 180000000 millimetres per second is equal to 180000000 x 3600 = 648000000000 millimetres per hour.

There are 100000 millimetres in one kilometre. Therefore, 750000 millimetres per second is equal to 750000/1000000 = 0.75 kilometres per second. There are 3600 seconds in one hour. Therefore, 0.75 kilometres per second is equal to 0.75 x 3600 = 2700 kilometres per hour.

63 miles per second = 365,000 kilometers per hour.

There are 3600 seconds in one hour. Therefore, something travelling at 15000 millimetres per second is travelling at 15000 x 3600 = 54000000 millimetres per hour. There are 25.4 millimetres in one inch. Therefore, rounded to two decimal places, 54000000 millimetres per hour is equal to 54000000/25.4 = 2125984.25 inches per hour.

50 kilometers per hour is equal to 13,888.9 centimeters per second.

About 90 Kilometers.

There are 100000 millimetres in one kilometre. Therefore, 750000 millimetres per second is equal to 750000/1000000 = 0.75 kilometres per second. There are 3600 seconds in one hour. Therefore, 0.75 kilometres per second is equal to 0.75 x 3600 = 2700 kilometres per hour.

The answer is follows: 750 000 millimetres per second is equal to 0,75 kilometres per second. There are 60 minutes in an hour and 60 seconds in each minute,therefore 0.75 km * 60 * 60 = 2 700 km/h

63 miles per second = 365,000 kilometers per hour.

There are 3600 seconds in one hour. Therefore, something travelling at 15000 millimetres per second is travelling at 15000 x 3600 = 54000000 millimetres per hour. There are 25.4 millimetres in one inch. Therefore, rounded to two decimal places, 54000000 millimetres per hour is equal to 54000000/25.4 = 2125984.25 inches per hour.

both are equal. 60 kilometer in a second=60X60X60 meters in an hour=60X60X60/1000 kilometers in an hour=216 kilometers in an hour.

There are 1,000 millimetres in a metre. There are 3,600 seconds in an hour. So to convert you need to multiply by 1,000 and again by 3,600. 100 metres per second = 100,000 millimetres per second. 100,000 millimetres per second = 3,600,000 millimetres per hour.

54 kilometers per hour is equal to 15 Meters per Second so 30 meters per second

Neither; they are equal.

50 kilometers per hour is equal to 13,888.9 centimeters per second.

400 miles per hour is 586.7 feet per second or 643.74 kilometers per hour.

The speed of 140 kilometers per hour is equal to 86.99 miles per hour. It is also equivalent to 1.45 miles per minute or 127.6 feet per second.

Kilometer is distance, hours and minutes are time. There's no way to exchange one for the other.
