Over Lesson 6–2 5-Minute Check 1 A.Her rate on Monday was 2 miles per hour slower than her rate on Tuesday. B.Her rate on Tuesday was 2 miles per hour slower than her rate on Monday. C.Her rate on Monday was the same as her rate on Tuesday. D.Her rate on Tuesday was 2 miles per hour faster than her rate on Monday. On Monday, Ms. Moseley drove 340 miles in 5 hours. On Tuesday, she drove 198 miles in 3 hours. Based on these rates, which statement is true?

Then/Now You have already learned to find unit rates. (Lesson 6–2) Convert between systems of measurement.

Vocabulary dimensional analysis – the process of including units of measurement when computing

Concept

Example 3 Convert Measurements Between Systems A. Convert 4 inches to centimeter. Round to the nearest hundredth. Use 1 inch ≈ centimeters. Divide out common units, leaving centimeters. Simplify. 4 in ≈ ≈ cm Answer: So, 4 inches is approximately centimeters. 4 in 1 x cm 1 in

Example 3 Convert Measurements Between Systems B. Convert 15 meters to feet. Round to the nearest hundredth. Use 1 m ≈ ft. Divide out common units, leaving feet. Simplify. Answer: So, 15 meters is approximately feet.

Example 3 A m B.1.53 m C.1.70 m D m A. About how many meters are equal to 5 feet?

Example 3 A.3.31 qt B.7.66 qt C.7.40 qt D qt B. About how many quarts are equal to 7 liters?
