Answer:

239.92

Step-by-step explanation:

53.94×4=215.92

Then you do 21×2=24 then you take the 215.92 and the 24 and add them together and it gives you 239.92

The magnification of a telescope is the ratio of its focal length to the focal length of the eyepiece in use. Thus a telescope with a 1000 mm focal length, used with an eyepiece of 25 mm focal length, has a magnification of 1000 / 25, or 40. It makes things look 40 times wider, or if you prefer, 40 times closer.
