Question

Last year, David biked d miles. This year, he biked 475 miles. Using , write an expression for the total number of miles he biked?

Answer 1

The total number of miles David biked over two years is expressed as 'd + 475', combining last year's distance 'd' and this year's 475 miles.

Step-by-step explanation:

The expression for the total number of miles David biked last year and this year combined is d + 475. To calculate the total distance, simply add the number of miles biked last year, represented by the variable d, to the 475 miles he biked this year. This results in an expression for the total distance biked over the two years.
