375 g. You have to set up a proportion and cross multiply.
400% is because 125 divided by 500 is 400
X= 65
I don't really know how to solve it but that's the answer, sorry
Hey!
So what you can do is:
1 x 1.5 = 1.5(2nd term)
1.5 x 1.5=2.25(3rd term) x 1.5=3.375(4th term) x 1.5 = 5.0625(5th term)
5.0625 x 1.5=7.59375(6th term)x1.5=<span> 11.390625
</span>11.390625 x1.5= 17.0859375(8th term)x1.5=<span> 25.62890625</span>(9th term)
The answer is D!
Hope this helps!
speed of plane flying east = x
speed of plane flying west = x+75
total speed = 2x+75
distance after 4 hours ( 7-3) = 8x+300
8x+300 = 5460
8x = 5160
x = 5160/8 = 645
speed of plane flying east = 645 km/h
