What Math Concepts are taught in Eighth Grade? Eighth grade begins with reviews from following years such as problem solving, reasoning, and estimates. They will also use problem-solving strategies such as reading the problem, drawing a picture or diagram, using trial and error, making a table or chart, looking for patterns, making a simple problem then generalizing, working backwards, etc.  Grade 8 math word problems with answers are presented. Also solutions and explanations are included. A car traveled miles in 4 hours 41 minutes. What was the average speed of the car in miles per hour?

Pump B can fill the same tank in 8 hours. How long does it take the two pumps working together to fill the tank? A water tank, having the shape of a rectangular prism of base square centimeters, is being filled at the rate of 1 liter per minute.

Find the rate at which the height of the water in the water tank increases. Express your answer in centimeters per minute. The size of the perimeter of the square ABCD is equal to cm. Water is being pumped, at a constant rate, into an underground storage tank that has the shape of a rectangular prism.

Which of the graphs below best represent the changes in the height of water in the tank as a function of the time? Initially the rectangular prism on the left was full of water. Then water was poured in the right cylindrical container so that the heights of water in both containers are equal.

Find the height h of water in both containers. Peter drove at a constant speed for 2 hours. He then stopped for an hour to do some shopping and have a rest and then drove back home driving at a constant speed. Which graph best represents the changes in the distance from home as Peter was driving?
