Question

: A man is walking at a speed of 10 km/h. After every km, he takes rest for 4 minutes. How much time will he take to cover a distance of 10 km?​

Answer 1

Answer:

Total time (cover a distance of 10 km) = 96 min.

Explanation:

Given :

• Walking speed of man = 10 kmph

• After every km, he takes rest for 4 minutes

To find :

• Time taken by him to cover a distance of 10 km

Solution :

Total time (journey)

t = d / s

t = 10 / 10

t = 1 hrs (60 min)

After every km, He takes rest for 4 minutes

So,

Total delay in 9 stop (9 × 4)

Break time : 36 min.

Total time (to cover a distance of 10 km) :

⇒ 60 min + 36 min

⇒ 96 min (1 hrs 36 min)

Therefore,

Total time (cover a distance of 10 km) = 96 min.

Answer 2

Given:-

⠀⠀

A man is walking at a speed of 10 km/h. After every km, he takes rest for 4 minutes.

⠀⠀

To Find:-

⠀⠀

How much time will he take to cover a distance of 10 km?

⠀⠀

STEP BY STEP EXPLANATION:-

⠀⠀

Total time covered in the journey

⠀⠀

$\bf \: \: \: \: \: \: \implies t = \frac{d}{s} \\ \\ \bf \implies t = \frac{10}{10} \\ \\ \bf \implies t = 60 \: min$

⠀⠀

Now, he takes rest of 4 minutes

⠀⠀

delay on 9 stop ( 9 × 4 )

⠀⠀

the break time is = 36 min

⠀⠀

Total time will be take to cover 10 km

⠀⠀⠀⠀

60 min + 36 min

⠀⠀

96 min

⠀⠀

$\sf \therefore Hence ,he \: will \: take \: 96 \: min \: to \: cover \: 10 \: km$
