X travelled a distance of 75 km in 8 hours. He travelled partly by foot @ 5 km/h and partly on bicycle @ 12 km/h . Find the distance that X covered on foot.

Solution & Step-by-step Explanation

Let the time spent travelling on foot be t hours. Then, the time spent on the bicycle = (8 - t) hours. We know that: Distance = Speed \times Time According to the question: 5 t + 12 (8 - t) = 75 5 t + 96 - 12 t = 75 - 7 t = 75 - 96 - 7 t = - 21 ⟹ t = 3 hours Therefore, the distance covered on foot: Distance on foot = 5 \times 3 = 15 km
