<h3><u>Given</u>:</h3>

A man travels from A to B at 4 km/h and from B to A at 6 km/h

Total time taken = 45 minutes

<h3><u>Formula</u>:</h3>

Speed = Distance ÷ Time

60 minutes = 1 hour

So, To convert minutes to hour Divide it by 60,

= 45/60 = 3/4 hour

Let the distance between point A to B be x

So, According to question

x/4 + x/6 = 3/4

6x + 4x/24 = 3/4

4(10x) = 24(3)

40x = 72

40x/40 = 72/40

x = 1.8 km

Thus, The distance travelled by the man from point A to B is 1.8 km

How many solutions does the following system of equations have?<br> y=5/2x+2<br> 2y= 5x +4
goldfiish [28.3K]

Answer:

infinite solutions

Step-by-step explanation:

y=5/2x+2

2y= 5x +4

Multiply the first equation by 2

y = 5/2 x +2

2y = 5/2 *2 x +2 *2

2y = 5x +4

Since this is identical to the second equation (they are the same), the system of equations has infinite solutions
