Question

part a. decimal lengths (multi - step)
add or subtract the lengths. some problems require more than one step.

1. a hiking trail is 4.75 km long. you walk 1.68 km in the morning and 2.4 km in the afternoon.

how much farther do you need to walk to finish the trail? ___________ km

Explanation:

Step1: Calculate total distance walked

First, we need to find the total distance walked in the morning and afternoon. This is done by adding the two distances: \(1.68 + 2.4\).
\(1.68 + 2.4 = 4.08\) km.

Step2: Calculate remaining distance

To find out how much farther we need to walk, we subtract the total distance walked from the length of the trail. The trail is \(4.75\) km long, so we do \(4.75 - 4.08\).
\(4.75 - 4.08 = 0.67\) km.

Answer:

\(0.67\)
