Speed of sound in kms-1 = 0.3432 kms-1
distance = rate * time 1000 meters = 331 meters/second * x seconds x = 1000 / 331 So about 3 seconds.
1 minute =60 sec so, 1 km min =60 km sec
there are many things wrong with this question. first, its Tons, not tonnes. second, a kilometer and tons are not even the same measurment! What are you, in second grade!!!!???!!!
If it covers 92 meters in one second one needs to work out how many 92 meters there are in 1 Kilometer and this will be the number of seconds required to travel 1 Kilometer. There are 1000 meters in a kilometer thus 1000/92 = 10.87 so it will take the train 10.87 seconds to travel 1 kilometer.
Sound energy is produced by vibrating objects, which convert mechanical energy into sound waves. The sound waves travel through a medium, such as air or water, to reach our ears and be perceived as sound.
80.0 (km per hour) = 0.0138082487 miles per second.
2191.21 meters per second.
Sound travels at approximately 1500 meters per second in water.
There are 39,370,079,000 microinches in a kilometer.
Eight.
1 mile=1.609344 kilometers 5.644 miles x 1.609344=9.083137536 kilometer per second
A boron atom has three electrons in its second energy level.
