72 km/h is moving fast. because if 72 km/s should be converted into m/s by multiplying with 1000 and dividing with 3600. so 72km/s converts into 20m/s and 20m/s of speed of bus is more than a car moving with speed 12.5 . so bus is moving fast than car with speed 72km/s or 20m/s
Nikki57:
explanation?
if 72km/s is converted into m/s.then it will be 0.33m/s.
sorry answer is 72km/s
Then also explanation needed in the answer itself.
because if km/s is converted into m/s it will be 20m/s not 0.33m/s
Correct in the answer

to compare the speeds we should first bring both the values in the same unit system,
i m converting first one into metres/second
72km/hr = 72*(5/18)= 20 m/sec
now u can compare both the values.
speed of bus =20 m/s
speed of car=12.5m/s
hence, bus is moving faster
