To estimate how many miles Malcolm has left to drive, we first round each distance to the nearest ten. For the first day, 418 miles rounds to 420 miles, and the second day’s 384 miles rounds to 380 miles. Adding these two rounded distances gives us 420 + 380 = 800 miles driven so far. Now, subtracting this from the total distance of 1,273 miles: 1,273 - 800 = 473 miles. Therefore, rounding to the nearest ten, Malcolm has about 470 miles left to drive.

To ensure clarity, it’s always good practice to estimate using rounded numbers when approximating distances. This helps simplify calculations and allows you to focus on the bigger picture rather than getting bogged down by exact figures. In this case, it brings Malcolm’s travel to a manageable estimate!
