Question

-1by2 + y is equal to 1 find the value of y​

Answer 1

Answer:

As speed = DIST / TIME

Let x be the time of her school so by equation

4kmph = DIST / (x+5)

I.e 4(x+5) = d …….(1)

As she was late 5 mins hence x+5

For 2nd case

6 KMPH= DIST / (x-10)

I.e 6(x-10)=d……(2)

As LHS are equal , hence

4(x+5)=6(x-10)

4x+20=6x-60

80=2x

X= 40

Answer 2

$\frac{ - 1}{2} + y = 1$

$y = 1 + \frac{1}{2}$

$y = \frac{2 + 1}{2}$

$y = \frac{3}{2}$
