Rita has already cycled 4.65 kilometers this year, plus she plans to cycle 1 kilometers during each trip to work. After 42 trips to work, how many kilometers will Rita have cycled in total?

Answer 1

Let "n" be the number of times she cycles to work. Let "D" be the total distance (in km) she has traveled this year.

Then D = 4.65 + 1•n

or (because you don't really need to write the "1")

D = 4.65 + n
