Here's the solution to your problem:

a) Determine the length of the train in metres.

  1. Identify the given speeds and time.

    Speed of train, VT=25 km/hrV_T = 25 \text{ km/hr}
    Speed of truck, VTr=30 km/hrV_{Tr} = 30 \text{ km/hr}
    Time taken to overtake, t=112 minutes=1.5 minutest = 1 \frac{1}{2} \text{ minutes} = 1.5 \text{ minutes}
    Length of truck, LTr=5 mL_{Tr} = 5 \text{ m}

  2. Calculate the relative speed of the truck with respect to the train.

    Since they are moving in the same direction, the relative speed is the difference in their speeds
