Tanu is walking at a speed of 10 km/h. After every kilometer she takes a rest for 10 minutes. The time taken to cover a distance of 5 km by Tanu is:
Answer & explanation
Correct answer: option 3
Distance = Speed × Time
Time taken without any stoppage = \(\frac{ 5 }{ 10 }\) = 30 min
To cover 5 km , number of stoppage = 4
Time of rest = 4 × 10 = 40 min
Total time taken = 30 + 40 = 70 min
= 1 hour 10 min
The correct answer is Option (3) → 1 h 10 minutes
