At 9:00 a.m. Monday morning, Thomas fills a beaker with water and places it in the corner of the classroom. At 1:00 p.m. on Tuesday, Thomas examines the beaker and notices that the water level is 42 milliliters. At 11:00 a.m. on Wednesday, the water level has dropped to 31 milliliters. If the evaporation of the water follows a linear function, at what time will the beaker be empty?

Respuesta :

In 22 hours the level of water has went down by 11 millimeters. 22 divided by 11 is (.5). Multiply 31 by 2 which gives you 62. This means that in 62 hours the beaker will be empty. 62 divided by 24 (hours in a day) pans out to 2 days and 14 hours which means that on Saturday at 1am, the beaker will be empty. Counting from 11:00am on Wednesday.
