6. The cost of the vehicle operation and time for unit distance may be represented by __________
a) T=a+b+c
b) T=a+ (b+c)/speed
c) T=a+b
d) T=a

Explanation: ‘a’ is the running cost per unit distance, ‘b’ is a fixed hourly cost and ‘c’ is the portion of cost depending on speed.

7. The rate of fuel consumption for every motor cycle will be at __________
a) Low speed
b) High speed
c) Optimum speed
d) Zero speed

Explanation: The optimum speed is a speed limit in which neither the bike is going fast nor slow, it usually is between 30-45 Kmph for bikes.

b) UI=IRI/2
c) UI=IRI/3
d) UI=(IRI)1.12

Explanation: The UI is the unevenness index and IRI is the international roughness index, UI is in mm/km and IRI is in m/km.
