Hello @israa88 :)

I can see how this problem can be a little confusing, so I will do the best I can to help you out! :)
We can start with this, that the 3 kilometers that they start apart with should Not be attached to any letter and Should be in the equation

Answer 3

so now we are left with b or d

Answer 4

right :)

then we have to decide whether those two numbers should be addition or subtraction :/ hmm So think of it this way, if they are walking Towards each other, then they would be closing in on each other Faster (additive)

It takes 8 minutes for Byron to fill the kiddie pool in the backyard using only a handheld hose. When his younger sister is impatient, Byron also uses the lawn sprinkler to add water to the pool so it is filled more quickly. If the hose and sprinkler are used together, it takes 5 minutes to fill the pool. Which equation can be used to determine r, the rate in parts per minute, at which the lawn sprinkler would fill the pool if used alone?

Answer 17

5/8+ 5r = 8
5/8 + 5r = 1
5(2) = r
5/8= 5r
