Question

The ratio of distance between point A and B to the distance between point B and C is 3:4. If it take 18 minutes to walk from A to B at a speed of 3 Km/hr, how long will I need to walk from B to C at the same speed? Please don't send wrong answer its urgent please ​

Answer 1

$\huge{\red{\bold{\boxed{\ulcorner{\star\:Answer\: \star}\urcorner}}}}$

Ratio of the speeds of A and B = 2 : 3.

Let the speed of A=2x  km/min

Hence the speed of B=3x  km/min  

B takes 24 minutes to cover some distance.

Hence,  Distance=Time×Speed=24×3x=72x

For A,  

Time= Speed ÷ Distance

​

= 2x ÷ 72x

​ =36

Hence, the time taken by A to cover the same distance is 36 minutes.

Answer 2

Step-by-step explanation:

In tissue: Plants. Primary dermal tissues, called epidermis, make up the outer layer of all plant organs (e.g., stems, roots, leaves, flowers). They help deter excess water loss and invasion by insects and microorganisms. The vascular tissues are of two kinds: water-transporting xylem and food-transporting phloem.
