A person travels equal distances with speeds of 4 km/hr, 5 km/hr and 6 km/hr and takes a total time of 37 minutes. The total distance (in km) is
A4
B5
C3
D2
Answer:
C. 3
Read Explanation:
Let the equal distances he travels be 'd'
Total time = 37 minutes = (37/60) hours
d/4+d/5+d/6=37/60
37d = 37
⇒ d = 1 km
⇒ Total distance = 3 × 1 = 3 km
