A man completes a journey in 16 hours. He travels at a speed of 15 km/h for the first half of the journey and at a speed of 25 km/h for the second half. Calculate the total distance travelled (in km).
Answer & explanation
Correct answer: option 4
Total time = 5 + 3 = 8 Units
8 Units → 16 hours
1 Unit → 2 hours
75 Units → 75 × 2 = 150
Total distance = 150 × 2 = 300 km
