The terms should be converted into M.K.S units, as it is considered as the S.I. unit.
Converting 100km/h into m/s:
100km/h=27.8m/s (estimated)
1hour=3600 seconds
All the conversions are in M.K.S units
Calculation:
d=s*t
=27.8*3600
=100080.0 m (estimated)
This answer is only valid if the car is travelling uniformily.

Speed = Distance travelled / Time taken.
Speed of car = 120/2.5 = 48kmph.
Speed of truck = 192 / 3.5 = 54.85 kmph
Ratio = 120/2.5 : 192 /3.5
= 120/192 * 3.5/2.5
= 5/8 * 35/25
= 5/8 * 7/5
= 7/8
= 7 : 8 .
Thanks for the awesome question :D !
