Question

Malcolm is driving 1, 373 miles from Wichita to Charleston for a family reunion. He drives 468 miles the first day and 434miles the second day. Round each distance to the nearest ten and estimate about how many miles Malcolm has left to drive.

Answer 1

This problem describes two parts of a trip, on the first day the trip was 468 miles long, and on the second day, it was 434 miles long. We need to calculate how far from the destination the driver is from their destiny after the second day, knowing that the whole trip is 1373 miles long.

The first step we need to take, is to round the distances for each day to the nearest ten, this is done below:

`\begin{gathered} \text{ day 1}\cong470\text{ miles} \\ \text{ day 2}\cong430\text{ miles} \end{gathered}`

Now we need to subtract the distances for each day from the total distance:

`\begin{gathered} \text{ distance left}\cong1373-470-430 \\ \text{ distance left}\cong473 \end{gathered}`

The driver needs to drive approximately 470 miles to complete the trip.
