Answer:
12 km
Step-by-step explanation:
- 5h 24min = 5.4 hr
- time = distance / speed
--------------------------------
time out + time back = total time
d/5 + d/4 = 5.4
multiply both sides by 20 to clear the fractions
4d + 5d = 108
9d = 108
Divide both sides by 9
d = 12 km
Answer (explanation):
Step 1: Make sure the bottom numbers (the denominators) are the same.
Step 2: Add the top numbers (the numerators), put that answer over the denominator.
Step 3: Simplify the fraction (if needed)
Slope= rise/run
which is 4/2
4 decided by 2 is 2
so the slope is 2. also i LOVE ur pfp :)))
