Answer 2

Answer:

199 km 591 m

Step-by-step explanation:

for easy calculation arrange systematically

            278 km       1000 m

          -   78 km        409 m

          199 km         591 m

the 1000 m is borrowed from the 278 km leaving it as 277 km. then subtract the 78 km from the remaining 277 km remember to cancel to show that you've borrowed. hope you've understood
