Give each rate in miles per hour. Round to the nearest tenth.
Dhruv jogs 8 feet per second.
I don’t know the answer please help.
The question requires changing feet per second into miles per hour
The unit rate in miles per hour is 5.5 miles per hour
8 feet = 0.00151515 miles
1 second = 0.000277778 hour
unit rate in miles per hour = number of miles / number of hours
= 0.00151515 mile / 0.000277778 hour
= 5.4545356363714 miles per hour
Approximately, 5.5 miles per hour to the nearest tenth

Shontelle has soccer practice on Thursday evening. She has a half hour before practice to work on her math homework and talk to her friends. She has 20 math skill-work questions for homework, and she wants to complete them before talking with her friends. If she can solve three math problems in four minutes when she really focuses with no distractions, how many minutes will Shontelle have left after completing her math homework to talk to her friends.

Answer:
y = x - 3
Step-by-step explanation:
Answer:
Y= x-3
Step-by-step explanation:
The distance from our y values is -1.
The distance from our x values is -1.
Rise/ Run = Y/X
-1/-1 = 1 or 1/1
You would rise 1 and run 1!
You can use this strategy if you're using graph paper to eventually get the y intercept which is -3.
