When a formula produces output that is too lengthy to fit in the spreadsheet cell, the error that will show is "#####". When you enter an invalid cell reference in a formula, for instance using "AVE(" instead of "AVERAGE("; the error that will show is "#NAME?". When you type text in cells that accept numeric data, for instance adding 1 + 1 + A; then the error that will show is "#VALUE". Lastly, when you type in a cell reference that does not exist, the error that will show is "#REF".

It happens to me as well. Maybe check emails? It could also be a bug.
Explanation:
Designers are also responsible for interactive designs where the content changes as it gets updated, as well as screen interfaces that help people navigate through a lot of information. Interaction design differentiates itself from other kinds of design by adding another consideration: responding to the actions of the viewer or user. Editorial design for web and mobile is the most tangible example, including websites and mobile apps for publication. Some digital design involves the presentation of rapidly changing streaming information, also known as data visualization, creating both interactive and non-interactive interfaces. Product design refers to the
let's say they catch-up to each other after t hour.
so
in t hour distance travelled by Renee
d = speed × time = 50t
in t hour distance travelled by Kim
d = speed × time = 60(t-1) + 0×1 = 60(t-1)
Note: here kim didn't covered any distance in first hour and in rest t-1 hour it travelled all distance
now.as distance travelled by both is same so
60(t-1) = 50t
60t -60 = 50t
adding 60 both sides
60t = 50t+60
subtracting 50t both sides
60t -50t = 50t+60 - 50t
10t = 60
dividing by 10 both sides
t = 60/10 = 6
so in 6 hour both will catch-up to each other
