Chapter 2: Problem 12

Solve each problem by applying the four steps of problem solving. Use the strategy of solving an algebraic equation for each problem. You need to drive 440 miles to get to your best friend鈥檚 wedding. How fast must you drive to get there in 8 hours?

Short Answer

Expert verified
Answer: 55 miles per hour.

Step by step solution

01

Write the equation

The formula to find the speed is distance = speed 脳 time. We know the distance (440 miles) and time (8 hours), so we can write the equation as: 440 = speed 脳 8.
02

Solve for speed

To find the speed, we need to isolate the speed by dividing both sides of the equation by 8: \[ \frac{440}{8} = \frac{speed \times 8}{8} \]
03

Calculate the answer

Now we can simplify the equation and find the required speed: \[ speed = \frac{440}{8} = 55 \]
04

Write the conclusion

In order to get to your best friend's wedding in 8 hours, you must drive at a speed of 55 miles per hour.
