Question

A man is walking at a speed of 10 km/hour. After every kilometer he takes rest for 5 min. How much time will be taken to cover a distance of 5 km?​

Answer 1

Time required to travel 1 km is 1/10 hr= 60/10 minutes = 6 minutes. Do he actually takes 6+ 5 =11 minutes to complete on km til 4km . So time to complete 4 km is 4*11= 44 minutes .for last one km it will be 6 minutes as time for rest is not to consider after reaching 5 km. So total time is 44+6=50 minutes.

Answer 2

Answer:

$50 \: minutes$

Step-by-step explanation:

$time \: taken \: in \: covering \: 5 \: km$

$= \frac{5}{10}$

$= \frac{1}{2} \: hour$

$30 \: minutes$

That person will take rest for four times.

That person will take rest for four times.∴ Required time

$= (30 \times 4 \times 5) \: minutes$

$= 50 \: minutes$

Hence, 50 minutes is the answer.
