# A farmer travelled a distance of 61 km in 9 hours. Partly on foot @ 4 km/hr

A farmer travelled a distance of 61 km in 9 hours. partly on foot @ 4 km/hr and partly on bicycle @ 9 km/hr. The distance travelled on foot is:

- 14 km
- 15 km
- 16 km
- 17 km

**Answer: (3) 16 km**

**Solution:-**

Let the distance traveled on foot be X km.

Then, distance traveled on bicycle = (61 – X) km

According to the question,

So, X/4 + (61 – X)/9 = 9 x 36

(9 X + 4 x 61 – 4 X) = 9 x 36

5 X + 244 = 324

5 X = 80

X = 80/5

X = 16 km

Then, distance traveled on foot is 16 km.

Hence, the correct answer is option (3) 16 km.
