  1. A soldier walks 5 km at 4 km/h, then runs 10 km at 10 km/h. What is the total journey time?

    Answer: 2 hours 15 min

    Walking: 5 ÷ 4 = 1.25 hrs; Running: 10 ÷ 10 = 1 hr; Total = 2.25 hrs = 2 hours 15 min.

  2. Vehicle A leaves at 09:00 travelling at 60 km/h. Vehicle B leaves the same point at 10:00 travelling at 90 km/h in the same direction. When does B catch A?

    Answer: 12:00

    A has a 60 km head start; relative speed = 30 km/h; Time to catch = 60 ÷ 30 = 2 hrs after B departs = 12:00.

  3. A drone covers 450 km at 150 km/h. How long is the flight?

    Answer: 3 hours

    Time = 450 ÷ 150 = 3 hours.

  4. A convoy averages 40 km/h for the first 2 hours and 60 km/h for the next 3 hours. What is the total distance?

    Answer: 220 km

    First leg: 40 × 2 = 80 km; Second leg: 60 × 3 = 180 km; Total = 260 km.

  5. A soldier must cover 100 km. He cycles the first 40 km at 20 km/h and drives the remaining 60 km at 60 km/h. What is the total time?

    Answer: 2 hours

    Cycling: 40 ÷ 20 = 2 hrs; Driving: 60 ÷ 60 = 1 hr; Total = 3 hours.

  6. If a vehicle's speed is doubled, what happens to the time needed to cover the same distance?

    Answer: Time is halved

    Time = Distance ÷ Speed; doubling speed halves the time required.
