If the question is 75km/hr or 15 m/sec then answer is:
75 km/hr = 75 * 1000 /(60 *60)
= 75000/3600
= 20.83 m/sec
therefore
75 km/hr > 15 m/sec.

15 miles per second is 900 miles per minute. That is, 15 miles per second multiplied by 60 seconds in a minute. Multiply this by 60 again for the number of miles in an hour. I believe that you will see that 15 miles per second is definitely faster than 75 k/m per hour.

If you want to know which one is greater, all you have to do is to convert the unit of km/hr into m/s
75 km / hr = 75 km x (1000 m) / (1 km) x (1/hr) x (1 hr) / (3600 s)
= 20.8333 m/s
(1000 m) / (1 km) means that 1 km = 1000 m
(1 hr) / (3600 s) means that 1 hr = 3600 s
Therefore, we will know that 75 km / hr is the greater.

convert 15 m/sec o km/h to make the two unit same. U have to compare an apple to an apple rite?
15m/sec = 15 X 3600sec / 1000 km
= 54 km/h
so...its the first one...75km/h that is faster

(15*60*60)/1000 < 75
so 75 km/h is faster

15 meters per second is 54,000 meters per hour (54 KMPH)
so 75 kmph is greater

75 km/h is faster because it is 20.8 m/s
while 15 m/s is 54 km/h

75 km/hour

I assume you mean 75km/min=75,000 m/(60 sec) or
1250 m/s which is much faster than 15 m/s
