The problem provides a distance-time graph for Andy and Tom's canoeing race. We need to determine how much longer it took Tom to canoe the first 10 km compared to Andy, and express the answer in minutes.

1. Problem Description

The problem provides a distance-time graph for Andy and Tom's canoeing race. We need to determine how much longer it took Tom to canoe the first 10 km compared to Andy, and express the answer in minutes.

2. Solution Steps

First, read the graph to find the time each person reached 10 km.

According to the graph:

* Andy reached 10 km at approximately 12:

3

0. * Tom reached 10 km at approximately 13:

1

0.

Next, we need to calculate the time difference between when Tom and Andy reached the 10 km mark.

Time difference = Tom's time - Andy's time

Time difference = 13:10 - 12:30 = 40 minutes.

3. Final Answer

It took Tom 40 minutes longer to canoe the first 10 km than Andy.
