If a person walks at 14 km/hr speed instead of 10 km/hr, he would have walked 20 km more. The actual distance travelled by him is
(a) 50 km
(b) 56 km
(c) 70 km
(d) 80 km
Answer: (a) 50 km
Solution:-Let the time taken be X hr.
According to the question, 14 X – 10 X = 204 X = 20X = 20/4X = 5
Actual distance = 10 X = 10 x 5 = 50 km
Hence, the correct answer is option (a) 50 km.
