Question

5. A race course is 99 meters long. There are trees

along 38 meters of the course. How long is the part
of the course without trees?
unit

Answer 1

61 meters

Explanation:

To find this answer, you need to subtract the length with trees from the total length of the course. With this information, you get an equation that looks something like x + 38 = 99, with x being the length of the course without trees.

Subtract 38 from both sides:

x + 38 = 99

- 38 - 38

x = 99 - 38

Simplify:

x = 61

Answer 2

61

Explanation:

99 minus 38
