A boat travels at a constant speed. After 20 minutes, the boat has traveled 2.5 miles. The boat travels a total of 10 miles to a bridge.
a. How long does it take the boat to reach the bridge? Explain how you found it.

In order to find the speed at which the boat is traveling, we divide the distance it has traveled by the time elapsed:

2.5/20=0.125 miles/minute

Next, we want to find how long it took for the boat to travel 10 miles. Since it travels 0.125 miles every minute, we just divide:

10/0.125=80

Thus, it took 80 minutes for the boat to reach the bridge
