24 Km/h=24 km/h(1000 m/1Km)(1h/3600 s)=6.67 m/s.
10 minutes=10 minutes(60 s/1 minute)=600 s
Speed=distance / time
s=d/t ⇒d=st
d=(6.67 m/s)(600 s)=4000 m
Answer: 4000 m or 4 Km.
Other method:
1 hour ----------60 minutes
x------------------10 minutes
x=(1 hour 10 minutes)/ 60 minutes=1/6 h.
d=st
d=24 km/h 1/6 h=4 km.
Answer: 4 km.
