Let 'x' represent the total distance from point A to point B
During the first hour he gets 0.25 of the way there: 0.25x
During the second hour he covers an additional 0.2 of the distance: 0.2x
During the third hour, he covers 0.3 of the distance: 0.3x
The total distance the biker traveled is:
0.25x + 0.2x + 0.3x = (0.25 + 0.2 + 0.3)x = 0.75x
The biker has: x - 0.75x = (1 - 0.75)x = 0.25x of the total distance left to go.
Answer:
99
Step-by-step explanation:
102F down by 3F would be 99 and it says then. Then would be the 'two hrs later'.
Firstly we need to realize that "sea level" is the same as "surface of the ocean" and 0.
It means that Trina the scuba-diver is closer to the surface of the ocean than Jessie the glider because Trina is 85,5 meters from 0 level and Jessie is 87,9 meters from 0 level.
Now if Trina will hang glide at the altitude of 85,5, than she will <em>not </em>fly higher than Jessie (she will fly lower by 87,9 - 85,5 = 2,4 meters).
407 over 5 but it also has to be simplified
