Answer:

Step-by-step explanation:

To answer the question we must find the Time of B.

This should be easy considering the fact that we have are given the Distance and the Speed.

\frac{D}{S} = T

\frac{60}{40} = 1.5 hours or 1 hour and 30 minutes

Now, we know both routes that the same amount of time.

Now we know both routes take 1 hour and 30 minutes

Now we divide 90 by 1.5 to get our Speed for A

\frac{90}{1.5} = 60km/hr

ozzi

Answer:

Step-by-step explanation:

2x+5y=12

3x+4y=11

---------------

3(2x+5y)=3(12)

-2(3x+4y)=-2(11)

-----------------------

6x+15y=36

-6x-8y=-22

-----------------

7y=14

y=14/7=2

2x+5(2)=12

2x+10=12

2x=12-10=2

x=2/2=1

x=1, y=2. (1, 2)

---------------------

I just provided you an example of a system of equations and I already solved it for you.
