Amit is walking at a speed of 10 km/hr. After every kilometer, he takes a rest for 5 minutes. What is the time taken to cover a distance of 5 kilometers by Amit?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 50 minutes
Amit’s walking speed = 10 km/hr
So, time to walk 1 km:
$= \frac{1}{10}\text{ hr} = 6 \text{ minutes}$
Step 1: Time spent walking 5 km
$5 \times 6 = 30 \text{ minutes}$
Step 2: Rest time
After every kilometer, he rests 5 minutes.
To cover 5 km, rests are taken after 1st, 2nd, 3rd, and 4th km
(No rest after finishing the 5th km)
$4 \times 5 = 20 \text{ minutes}$
Step 3: Total time
$30 + 20 = 50 \text{ minutes}$
