Please help wit all questions! leave work below! if you do this , it will give you 40 points!!
Marta_Voda [28]

Answer:

13. ft per minute is 150. ft per hour is 9,000.

work:

  • 300÷ 2 = 150
  • 150 times 60 min.

14. x ÷ y = feet per minute.

it is this because the time divided by the depth will equal the time that it took.

15. it would be more reasonable to use feet by minute, because of the accuracy of the answers. with measuring it using feet per hour, your answers will be less precise.

16. the distance will double because the proportional relationship says that the distance is 3 km away if thunder is 9 secs apart from lightning.

will answer next question later
