please answer my question a girl runs a distance of 100 meters in 20 seconds. ca...

compactracer Here the given data
a girl runs
distance = 100 m
time taken = 20 seconds.

case one = speed of girl running per hour

one hour = 3600 seconds.
distance time
100m 20s
? 3600s
by cross multiplying we have
distance covered by the girl in one hour = 100 * 3600/20
= 18,000m
speed of the girl = distance / time
= 18000/3600
=50 m/s

case two
per minute.
one minute = 60 seconds
distance covered by the girl in one minute = 60 * 100/20
=300 m
speed of the girl = distance / time
= 300/60
= 5 m/s

case three
per second
distance travelled by the girl per second = 1 * 100/20
= 5m
speed of the girl = distance covered / time taken
= 5/1
= 5m/s
