Question

10км 2м-256м+8км 54м=? 15ч20мин-5ч45мин+6ч12мин?

Answer 1

1002м-265м+8025м=8763м

Answer 2

To solve the first equation, we need to add the distances and simplify:

10km 2m - 256m + 8km 54m

= (10km + 8km) + (2m - 256m) + 54m (grouping like terms)

= 18km - 254m + 54m (simplifying)

= 18km - 200m (combining like terms)

So, 10km 2m - 256m + 8km 54m is equal to 18km - 200m.

To solve the second equation, we need to subtract the times and simplify:

15h 20m - 5h 45m + 6h 12m

= (15h - 5h + 6h) + (20m - 45m + 12m) (grouping like terms)

= 16h 47m (simplifying)

So, 15h 20m - 5h 45m + 6h 12m is equal to 16h 47m.

Therefore, the solutions to the equations are:

10km 2m - 256m + 8km 54m = 18km - 200m

15h 20m - 5h 45m + 6h 12m = 16h 47m
