A person travelled a distance of 57 km in 9 hours. He travelled partly on foot at 5 km/hr and partly on bicycle at 8 km/hr. What is the distance travelled on foot?
Given:
Total distance = 57 km
Total time = 9 hours
Speed on foot = 5 km/hr
Speed on bicycle = 8 km/hr
Formula Used:
Distance = Speed × Time
Solution:
Let the time travelled on foot be t hours.
Then, time travelled on bicycle = 9 - t hours.
Distance on foot + Distance on bicycle = Total Distance
5 × t + 8 × (9 - t) = 57
5t + 72 - 8t = 57
72 - 3t = 57
3t = 15
t = 5 hours
Distance travelled on foot = 5 × 5 = 25 km
Final Answer
So the correct answer is (d)
