Explanation:
1. distance=25 km
time =0.5 h
speed = distance /time
=25/0.5
=250/5
=50km/h
2. distance=10km
time=1 h
speed = distance/time
=10/1
10km/h
3.speed=22km/h
time=10h
speed=distance /time
distance=(speed)(time)
=(22)(10)
=220km
4.speed=45km/h
distance=22km
speed =distance/time
time=distance/speed
=22/45h
5. distance=400m
time=2min
=2(60) sec
=120sec
speed=distance/ time
=400/120
=10/3km/h
6.speed=12m/s
distance=600km
=(600)(1000)m
speed=distance/time
time=distance/speed
=(600)(1000)/12
=(50)(1000)
=50000sec
7.distance=5km
=(50)(1000)m
time=50 min
=(50)(60) sec
=300sec
speed=distance/time
=(50)(1000)/300
=500m/s
