time and distance

d=s*t
s=10kmph=10*5/18 m/s
t=15min = 15*60 sec

d= 10(5/18)m/s * 900 sec [sec get cancelled]
d= 45000/18 m
d= 2500m

wrong answer

if u will convert time in hours then D=10*15/60=2.3km or 2300m .

t&d

convert 10 km/hr into meters by mul with 5/18
10*5/18=50/18
15 min into sec by mul with 60
(50/18)*15*60=2500
