Question

In our class, our class teacher gave us a project to complete in 15 days. If the teacher assigned 4 consecutive projects, how many days will you have to complete the projects?

Answer 1

Decided that I had originally interpreted the question incorrectly. Now updated to: Total time for 4 projects is 60 days

Explanation:

The question states: "`color(red)("a project")` to complete in 15 days"

a is 'singular' so one project is allowed 15 days

The wording "4 consecutive projects" means we have

4 lots of 1 projetct
4 lots of 15 days `->color(white)("d")ubrace(4)color(white)("d")xx15`
`color(white)(ddddddddddddddddd"d")darr`

same as `color(white)("dddddd")->2xxubrace(2xx15)`
`color(white)("dddddddddddddddddddd")darr`

`color(white)("dddddd.dddddd")->2xxcolor(white)(".d")30color(white)("d")=60`
