Which of the following pair of symbols will define the relation between Quantity I and Quantity II and between Quantity II and Quantity III respectively?
A. =
B. >
C. <
D. ≥ E. ≤ F. # (relation cannot be established) Quantity I: A bus takes the same amount of time to travel a distance of (d + 40) km at a speed of (s - 5) km/h as it does to travel (d + 160) km at a speed of (s + 5) km/h. It is also given that the bus covers (d -80) km in 16 hours when moving at 45 km/h. Determine how long the bus will take to travel (d - 50) km at a speed of s km/h. Quantity II: Two trains, P and Q, run from station X to city Y. Their speeds are 64 km/h and 72 km/h respectively. Train P departs from X, and 2 hours later train Q starts from the same point. Both trains reach Y at the same time. Determine the total time taken by train P to reach Y. Quantity III: A Motarboat goes 168 km upstream in 14 hours and 528 km downstream in 22 hours. If the Motarboat’s speed is increased by 8 km/h, Determine the total time it will take to travel 180 km upstream and 192 km downstream.
