Answer:
y=30, x=10
Step-by-step explanation:

Let the oranges cost = x
Let the apples cost = y
According to given conditions, equation becomes:
.... (1)
.....(2)
Multiplying equation (1) by 8 and equation (2) by 12 to get y
96x+48y=43.04 .... (3)
96x+60y=44.16 .... (4)
Now subtracting both equations we get,
12y = 1.12
y = 0.093
Hence, cost of 1 apple = $0.093
As 12x+6y=5.38
12x+6(0.093)=5.38
12x=4.822
x = 0.40
Hence, cost of 1 orange = $0.40
Answer:
30 h
Step-by-step explanation:
Formula
speed = distance/time
We clear time from it
time = distance / speed
time = ?
distance = 15 km
speed = 0.5 km/h
time = 15/ 0,5 = 30 h
