(i) Time = 2 hours
= 2*60
= 120 minutes
= 120*60
= 7200 seconds
speed = 1 metre per second
distance = speed * time
= 1*7200
= 7200 metres
= 7200 / 1000
= 7.2 kilometres
(ii) t =1.8 s
d = 8.5 m
s = d/t
= 8.5/1.8
= 4.72222 mps
= 4.72222*3.6
= 17 kmph
(iii) d = 24 km
= 24*1000
= 24000 m
s = 48.2 kmph
t = d / s
= 24/48.2
= 0.497925 h
= 0.497925*60
= 29.8755 m
= 29.8755*60
= 1792.53 s
