Question

find unit rate
a. 75 min for 100 meters

b. 19 gallons in 12 hours

Explanation:

Step1: Understand unit rate formula

Unit rate is calculated as $\frac{\text{Quantity 1}}{\text{Quantity 2}}$ where we want per 1 unit of Quantity 2.

Step2: Solve part a

For 75 min per 100 meters, unit rate (min per meter) is $\frac{75}{100} = 0.75$ min/meter.

Step3: Solve part b

For 19 gallons in 12 hours, unit rate (gallons per hour) is $\frac{19}{12} \approx 1.583$ gallons/hour.

Answer:

a. $0.75$ minutes per meter
b. $\approx 1.583$ gallons per hour
