A11 minutes

B12 minutes

C9 minutes

D10 minutes

Answer:

D. 10 minutes

Read Explanation:

First convert time into minutes:

4minutes10seconds=(4+1060=256)minutes4 minutes 10 seconds = (4 + \frac{10}{60} = \frac{25}{6}) minutes

Speed = Distance / Time
=(2.525/6=2.5×625=0.6)km/min= ( \frac{2.5}{25/6} = 2.5 \times \frac{6}{25} = 0.6 ) km/min

Now, time to cover 6 km:
Time=Distance/Speed=(60.6=10)minutesTime = Distance / Speed = ( \frac{6}{0.6} = 10 ) minutes

Final Answer: 10 minutes
