Dakar Rally (Unit Rate with Speed)

Welcome to the Dakar Rally, the world's most famous and most challenging rally race, racing across undeveloped terrains such as mountain passes and deserts. Driving hundreds of km a day, drivers and their vehicles are pushed to the limit. The rally tests their technique, mental and physical strength, mechanical skill, and experience to cover nearly 9,000 km in two weeks. More than half of the vehicles that begin the race fail to finish it, epitomizing the toughness of the rally. Stage 9 of this year's Dakar Rally covers a distance of 831 kilometers. Let's look at the virtual map to see the location of the teams in the race and their speeds. How long will it take each team to get to the finish?

Leaky Faucet (Unit Rates and Unit Conversion)

Sara and James are at their vacation home in the woods when Sara notices the hose bib on the side of the house is leaking water. The calcium buildup prevents the hose bib from completely closing. They could try to clean it or replace it. Sara wants to know how much water leaks out of this hose bib. James gets a stopwatch and measuring spoons and finds out 1 tsp leaks out of the hose bib every 6 minutes. How much water is that in a week, a month, a year?
