Answer 1

Answer:

Part A

0.764 minutes/miles

Part B

48.4 minutes

Step-by-step explanation:

a) Jasmine ran 55 miles in 42 minutes. Part A At what rate did Jasmine run?

​Jasmine ran at a rate of minutes per mile. ​

Rate = Minutes/Miles

Minutes = 42 minutes

Miles = 55 miles

Jasmine's rate = 42 minutes/55 miles

= 0.7636363636 minutes/miles

Approximately = 0.764 minutes/miles

Part B

Katie ran 44 miles. She ran at a rate that was 1.1 minutes per mile slower than Jasmine. For how many minutes did Katie run? Explain how you determined your answer. ​ ​

Rate = Minutes/Miles

Minutes = ?

Miles = 44 miles

Rate = 1.1 minutes per miles

Hence:

1.1 minutes per miles = x/44 miles

x = 1.1 minutes per miles × 44 miles

x = 48.4 minutes
