Let x be the rate of the slower bicyclist and
x + 4 be the rate of the faster bicyclist
Since the bicyclists are headed towards opposite directions, the sum of the distances they covered traveling for one hour and 15 minutes should be equal to 40 km based on the given conditions above. This may be expressed as,
(x)(1.25) + (x + 4)(1.25) = 40
Calculating gives x = 14
Thus, the rate of the bicyclists are 14 km/h and 18 km/h.
Answer:
<u>Line b</u>

Answer:
x = 8
Step-by-step explanation:
Assuming the figure is a parallelogram, the diagonals bisect each other. That means ...
3x -11 = x +5
2x = 16 . . . . . . . add 11-x to both sides
x = 8 . . . . . . divide by 2
We can’t measure these. How long is each of them
Answer:
