Question

a man travels 65 km in 3 days by walking 71 by half a day in how many days will the travel 156 km walking in 8 hours a day​

Answer 1

Answer:

Here's your answer

Step-by-step explanation:

$\huge \mathfrak \purple{answer}$

Distance travelled in 3 days is 65 km

Time taken to travel in these 3 days = 3×7 ½ hrs

= 3 × 15 ÷ 2

= 45 ÷ 2 hrs

Speed = Distance/Time

65 ÷ 45 ÷ 2

= 5 × 13 × 2 ÷ 5 × 9

= 26 ÷ 9 km/hr

Let 't' be taken time to travel 156 km

As distance = Speed × Time

156 = 26 ÷ 9 × t

t = 156 × 9 ÷ 26

t = 6 × 9

t = 54 hrs

As he travelled 8 hrs in 1 day

So, it takes 54 ÷ 8 days to travel 156 km

54 ÷ 8 = 27 ÷ 4

= 6 ¾ days

Hence, it takes 6 ¾ days to travel 156 km

And this is physics

Thank you

Answer 2

Answer:

Every day he walks 7.5 hrs

So in three days he walks 7.5×3 =22.5hrs

And he travelled 65km in these 22.5hrs

So the speed = distance/time

= 65/22.5 = 2.88km/hr

Speed of the man will remain same,

So time = distance/speed

= 156/2.88 = 54 hrs

Everyday he walks 8hrs, so for 54 hrs, he has to walk 54/8 = 6.75 days
