Question

If a person walks at 14 km/h instead of 10 km/h, he would have walked 20 km more. The actual distance travelled by him is

Options

• 50 km

• 56 km

• 70 km

• 80 km

Answer 1

50 km
Explanation:
Let the actual distance travelled by a person is x km.

Then, `x/10=(x+20)/14`

⇒ `14x=10x+200`
⇒ `4x=200`
∴ `x=50` km
