15 = 5 x 3 = 5 x √3 x √<span>3
so
15 / (5</span><span> √</span>3)
= (5 x √3 x √3)/ (5 x √3) ............( 5 x √3 are canceled out)
= √3
or
= 1.73
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.
9 x ≥ 117
Divide both sides by 9 :
9 x / 9 ≥ 117 / 9
x = 117 / 9
x ≥ 13
hope this helps!
