15,000
t = s/v s = 15 km v = 100 km/h t = 15 km/(100 km/h) = 0,15 h = 9 minutes.
15 nm (24 km)
About 10 minutes at 55mph
Length of unsharpened pencil is measured in cm . km is a bigger quantity.
we know,speed =distance /time . so,here time =15/80=0.1875 hr
8 hours 15 minutes
15 km = 15 000 mTo convert from km to m, multiply by 1000.
Light travels 300,000 km per second.It travels 15 km in (15 / 300,000) = 5 x 10-5 = 0.00005 second(0.005 millisecond, 50 microseconds)
1 hour 52.5 minutes.
1 m = 1/1,000 km (or 1 km = 1,000 m)15 m = 15/1,000 = 0.015 km
It will take 47 minutes and 15 seconds to drive that distance.
