What is the height of the shorter waterfall?
The average height of the waterfalls was 805 m.
The difference between the height of the waterfalls was 26 m.
What is the height of the shorter waterfall?
Penjelasan dengan langkah-langkah:
diketahui :
the average of waterfalls : 805 m
the height's difference : 26 m
ditanya :
height of the shorter waterfall?
dijawab :
average = sum of all values ÷ total number of value
misal :
the longer waterfall = x
maka :
=> the height's difference (26 m)
26 = the longer waterfall - shorter waterfall
26 = x - shorter waterfall
sorter waterfall = x - 26
=> average of waterfalls (805 m)
805 = (height longer waterfall + shorter waterfall) ÷ 2
805 × 2 = height longer waterfall + shorter waterfall
1610 = x + (x - 26)
1610 = 2x - 26
1610 + 26 = 2x
1636 = 2x
818 = x
=> height of shorter waterfall
= x - 26
= 818 - 26
= 792
So, the height of the shorter waterfall is 792 m.
