Chapter 1, Problem 76A

Interpretation Introduction

Interpretation : The time taken to empty the tanker is to be analyzed.

Concept Introduction : The methods for solving numerical problems are arranged into a three-step approach to problem-solving. Analyzing, calculating, and evaluating are the steps in solving a numerical word problem.

Answer to Problem 76A

The information that would be needed to find the time taken to empty the tanker is the number of gallons in a barrel.

Explanation of Solution

The analysis is one of the most important steps in solving a numerical problem.

First, establish the starting point (what is known) and the destination (what is unknown) to solve a word problem.

Planning is essential for effective problem-solving.

First, analyze the known information from the question.

The oil tanker contains 4,000,000 barrels of oil.

The rate of emptying is 5,000 gallons per minute.

The unknown is the time taken to empty the tanker.

But the given information is insufficient to solve the problem.

The relationship between gallons and barrels is not given.

The number of gallons in a barrel is the data to be given to calculate the time taken to empty the tanker.
