Answer :
The distance between first and second artifact which discovered buried beneath the ground at an elevation of meters is 27 [tex]\frac{2}{7}[/tex].
How to calculate the distance between two elevations ?
- Two artifacts buried was discovered beneath the ground, and the archaeologist found the two artifacts in two places at different elevation or heights. Then we are asked to find out the different elevations between the two.
- It is given that first artifact was found in depth -8:2/7 meters, and the second was found in depth at -35:4/7 meters inside. To find the different we can solve by bellow step;
- -8:2/7 - (- 35:4/7), we use a subtraction sign because what we are looking for was buried beneath the ground. Thus, this depth is represented with a minus sign like in the number line material.
- Then, it was pointed out that subtraction meets minus sign, when they meet we can either cancel it, and change it with positive sign or change the way of calculating it with addition.
= -8:2/7 - (- 35:4/7)
= -8:2/7 + 35:4/7
= 27 2/7.
- Then we can take a conclusion, the distance between those two elevation is 27 [tex]\frac{2}{7}[/tex] meters.
