1.	A person wants to travel a distance of 50 km by his bicycle. He travels with a speed of 12.5 km/hr. After every 12.5 km, he takes a rest of 20 minutes. How much time will he take to complete the whole distance? (a) 4 hrs 20 min (b) 5 hrs 20 min (c) 5 hrs (d) 6 hrs
Answer» (c) 5 hrs Time taken to travel 50 km = \(\frac{50}{12.5} hrs =4\,hrs.\) Number of stoppages = \(\frac{50}{12.5}-1=3\) ∴ Total duration of stoppages = (3 × 20) min = 60 min = 1 hrs ∴ Total time to complete the whole distance = 5 hrs.

Answer»

(c) 5 hrs

Time taken to travel 50 km = \(\frac{50}{12.5} hrs =4\,hrs.\)

Number of stoppages = \(\frac{50}{12.5}-1=3\)

∴ Total duration of stoppages = (3 × 20) min = 60 min = 1 hrs

∴ Total time to complete the whole distance = 5 hrs.
