The coordinate grid below shows the location of joe’s house, david’s house, and the community swimming pool. joe cycled in a straight line from his house to david’s house, and then together they cycle to the community swimming pool. what is the total distance in units that joe cycled?

36 units

Step-by-step explanation:

Each square present in the graph shows the distance of four units. Now it is defined in the question, that Joe always travelled in a straight line. So first he went to David's house. He travelled seven boxes to reach David's house.

Each box = 4units

So, for 7 boxes,

7 x 4 = 28 units (A)

Now they both went to swimming pool which is at the distance of two units from David's house

So they both travelled two boxes.

Distance from David's house to swimming pool is 2 boxes

Each box = 4units

2 x 4 = 8 units (B)

So total distance Joe travelled = A + B

total distance Joe travelled =  28 + 8

total distance Joe travelled =  36 units
