In this warm-up exercise, your friend drives to pick you up but forgets his wallet. Starting from his house, he travels 10 ¾ miles to realize his mistake and returns home. Using a number line and an addition algorithm, you can represent the total distance he drove. After retrieving his wallet, he drives another 20 ¾ miles to your house. To find the overall distance traveled and determine his rate in miles per hour (MPH), apply the formula R = D/T, converting fractions to decimals if necessary.

Warm UpRate Time/Complex Fractions Your friend has a car and is coming to pick you up to go to the mall. He leaves his house and drive 10 ¾ miles. He then realizes that he forgot his wallet so he returns home. Use a number line and addition algorithm to represent the total distance your friend drove.
Warm Up • Your friend then gets back in his car and drives the 20 3/4 miles to your house. • What was the total distance traveled including his previous trip? Use a number line to solve. You may also use an addition algorithm if needed. • If this took him 3 hours excluding the time at his house to get his wallet what was his rate in MPH? Hint: R X T = D and it may be easier to convert your fraction into a decimal in order to divide.
