The internet is a global network of interconnected computers and servers that communicate with each other through standardized protocols. It provides a platform for the exchange of information, resources, and services, enabling users to access websites, send emails, stream media, and engage in various online activities. The internet is often described as a vast information superhighway, facilitating communication and connectivity across the world.

To determine when the two runners, Sony and Mony, will meet at the starting point again, we can follow these steps:

1. Convert the speeds from km/h to m/s:

– Sony’s speed: ( 18 , text{km/h} = frac{18 times 1000}{3600} = 5 , text{m/s} )

– Mony’s speed: ( 24 , text{km/h} = frac{24 times 1000}{3600} = frac{24000}{3600} = frac{20}{3} = 6.67 , text{m/s} )

2. Calculate the relative speed:

– The relative speed when both are running in the same direction:

[ text{Relative speed} = text{Speed of Mony} – text{Speed of Sony} = 6.67 , text{m/s} – 5 , text{m/s} = 1.67 , text{m/s} ]

3. Determine the time taken to meet again at the starting point:

– The time taken for the faster runner (Mony) to gain a complete lap over the slower runner (Sony) can be calculated using the track length and the relative speed:

[ text{Time} =

To determine the value of (y) such that the numbers 39, 117, 17, and (y) are in proportion, we can set up the proportion as follows:

[

frac{39}{117} = frac{17}{y}

]

To solve for (y), we can cross-multiply:

[

39y = 117 times 17

]

Calculating (117 times 17):

[

117 times 17 = 1989

]

Now substituting back:

[

39y = 1989

]

Next, we’ll solve for (y) by dividing both sides by 39:

[

y = frac{1989}{39}

]

Calculating (frac{1989}{39}):

[

y = 51

]

Thus, the value of (y) is (51).
