Answer:
828.7 hours.
Step-by-step explanation:
To answer a question in which the total time has to be calculated of all the activities, first of all, all the times have to be converted to a single form. There are two types: decimals and fractions. Convert the fractions into decimals.
Department A = 202.50 hours.
Department B = 212 3⁄4 hours = 212.75 hours.
Department C = 198.25 hours.
Department D = 215 1⁄5 hours = 215.20 hours.
Therefore, the total number of hours spent on this project by all four departments. is the sum of all the above numbers. 202.50 hours + 212.75 hours + 198.25 hours + 215.20 hours = 828.7 hours.
Therefore, the total time is 828.7 hours!!!
