Step-by-step explanation:
1 km = 1000 m
Or
1 m = 1/1000 km
1 hour = 60 minutes
Or
1 minute = 1/60 hrs
1 minute = 60 seconds
Or
1 second = 1/60 minutes

Step-by-step explanation:
speed = distance / time
a) speed = 1500 km / 20 hr
= 75 km/hr
b) speed = 13350 km / 25 hr
=534 km / hr
here 9000 m = 9 km and 50 minutes = 5/6 hr
c) speed = 9 km / 5/6 hr
54/5 = 10.80 km/hr
d) 1 hour 40 minutes = 5/3 hr
speed = 2500 / 5/3
= 7500 / 5 = 1500 km/hr
e) 2 minutes 5 seconds = 125 seconds
speed = 100 / 125 = 4/5 = 0.8 m/s
