Practicing Success
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: |
1 h 20 minutes 1 h 5 minutes 1 h 10 minutes 1 h 12 minutes |
1 h 10 minutes |
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 |
