Jake ran 0.534 km in all, if he ran 145 meters before lunch and 389 meters after lunch.

Step-by-step explanation:

The given is,

                  Jake ran 145 meters before lunch.

                  389 meters after lunch.

Step:1

        Total distance ran by Jake,

           Total distance = Jake run before lunch + Jake run after lunch...(1)

        Where,

                    Jake run before lunch = 145 meters

                       Jake run after lunch = 389 meters

        Equation (1) becomes,

                    Total distance = 145 + 389

                                             = 534

                    Total distance = 534 meters

Step:2

        1 kilometer = 1000 meters

        Total distance ran by Jake = 534 meters

                                                     = kilometers

                                                     = 0.534

      Total distance ran by Jake  = 0.534 km

Result:

         Jake ran 0.534 km in all, if he ran 145 meters before lunch and 389 meters after lunch.
