Practicing Success
A person covers a distance of 32 km in 5 hrs . Some part of this journey is covered on foot at the speed of 6 km/hr and the rest by cycle at the speed of 8 km/hr. Find the distance covered on foot . |
18 km 36 km 24 km 34 km |
24 km |
Distance = Speed × Time Total Distance = 32 km Total Time taken = 5 hours Let the time he traveled on foot be x hours with speed 6 km/hr And time he traveled by bicycle is ( 5 - x ) hours with speed 8 km/hr According to question , 6 × x + 8 × ( 5 - x ) = 32 6x + 4o - 8x = 36 2x = 8 ⇒ x = 4 hours So , distance traveled by foot = 6 × 4 = 24 km |
