cosine ( CAH) = Adjacent/ hypothenus
cos9 = x/ 2
let x represent the horizontal distance
2 cos 9 = x
x = 2 (0.98768834)
x = 1.975
x = 1.97
therefore the horizontal dstance jade covers is 1.97km
Answer:- 
Step-by-step explanation:
The given ration is 16 :40
In fraction, the above ratio can be written as : 
To write the above fraction in lowest terms, we need to divide the numerator and the denominator by the greatest common divisor.
Since,
, Hence, 8 is the greatest common divisor of 16 and 40.
Now, divide the numerator and denominator by 8, we get

You can easily add while numbers but with decimals, if the point is put in the wrong place then you’ll change the entire number
