Question

a cyclist travels at an average speed of 25 kmph.how lonng will it take for him to travel a triangular journey through three places p1,p2and p3 ?​

Answer 1

Answer:

p1+p2+p3/25

Explanation:

Time=Distance/Speed

Distance=p1+p2+p3

Speed=25km/h

Time=p1+p2+p3/25

Answer 2

The total time taken for triangular journey is  $\dfrac{[tex]p_{1}$ + $p_{2}$ + $p_{3}$}{6.944]second.

Explanation:

Given,

Average speed = 25 kmph = 25 × $\dfrac{5}{18}\dfrac{m}{s}$

= 6.944  $\dfrac{m}{s}$

We know that ,

Average Speed = (Total distance covered throughout the journey) ÷(Total time taken for the journey)

∴ Total time taken for the journey = $\dfrac{Total didtance}{Average speed}$

= $\dfrac{[tex]p_{1}$ + $p_{2}$ + $p_{3}$}{6.944]  second

Hence,  the total time taken for triangular journey is $\dfrac{[tex]p_{1}$ + $p_{2}$ + $p_{3}$}{6.944] seconds.
