Question

A cyclist covers a distance of 2.5 km in 4 minutes 10 seconds. How long will he take to cover a distance of 6 km at the same speed?

• A. 11 minutes
• B. 12 minutes
• C. 9 minutes
• D. 10 minutes

Answer 1

Answer:

D. 10 minutes

First convert time into minutes:

$4 minutes 10 seconds = (4 + \frac{10}{60} = \frac{25}{6}) minutes$

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

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

✅ Final Answer: 10 minutes
