Jake is reading his light meter. The intensity, I , of lights varies inversely as the square of the distance, d , between the light source and the object illuminated. If the meter reads 0.25 units at a distance of 2 meters from the light source, what should it read at a distance of 3 meters from the source?

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75
