Answer:
3 km per hour
Step-by-step explanation:
You can deduct the answer instinctively since both the distance and the time of the descent are expressed in /5... so you can just get rid of the '/5' in both instances to get the result: 3 kilometers in 1 hour.
But you can also find it easily using the cross-multiplication system:
Then you multiply each side by 5 to get
3 km = 1 hour
Thus the rate of descent is of 3 km per hour.
Answer:
m = 1
b= -3
Step-by-step explanation:
Answer:
y = ½x - 1
Step-by-step explanation:
y + 3 = ½(x + 4)
y = ½x + 2 - 3
y = ½x - 1
13:39=13/39=0.333...=1/3=1:3
42
Explanation:12x2=24
9x2=18
24+18 =42
