a train is traveling at a speed of 68 mph.express its speed in meters per second.?

Question

how to convert miles per hour to meters per hour?

Answer 1

1 mile = 1.60934 km
and 1 km =1000 m

SO
68miles * 1.60934= 109..435 km
109.435 km * 1000= 109438 meters


1 hour = 60 * 60 sec
109438 / 3600 =30.399444

Answer 2

1 meter per second = 0.44704 miles per hour. Using this information we can use the factor label method with only one factor conversion:

68 mph * (0.44704 meters per second / mile per hour) = 30.39 m/s

Remember when you use the factor label method first write what you are given on the left of the = sign, and what you are trying to convert to on the right of the = sign. Then insert the appropriate factor conversions.

The long way to do this problem (using multiple factor conversions) would be...

(68 mi / 1 hr) * (1 mi / 60 min.) * (1 mi / 60 sec) * (1,609.344 m / 1 mile) = 30.39 m/s

Answer 3

am i doing your math homework? ;)

use this link...

http://www.onlineconversion.com/speed_common.htm

68 mile/hour (mph) = 30.398 72 meter/second

or the long way,

1 mile = 1609.344 meters
68miles= 109435.392

so the train is going 109435.392 meters per hour

so divide down the distance to get meters per second...

109435.392 /3600

= 30.3987 m/s

Answer 4

30.39222 meters/seconds

1 miles/hour = 0.44694 meters/seconds


sorry i dont like math

Answer 5

every one miles = 1650 metters

68M/h * 1650 m/M = 112200 metter per hour

112200/60 min /60 sec = 31.16

Answer 6

What has this got to do with chemistry? Looks more like homework help to me!

Answer 7

damn and i am being tested on this next week and i cant even tell u.... Go look up Nueton's Law of Motin! that'll work otherwise i am going to go hunting for my not's, if u want me to then IM me bak on inu_yasha_cutie

Answer 8
