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.

To solve this, multiply 3000 by 12%.
3000 x 12%
To convert percentages to decimals, divide them by 100 and remove the % sign.
So... 12% = 0.12
= 3000 x 0.12
= 360
Answer:
She would save £5
Step-by-step explanation:
→ First work out the cost of items for one student. Work out cost of the photocopying
40 × £0.02 = £0.80
→ Add the cost of the one folder
£0.80 + £0.70 = £1.50
⇒ Now we know £1.50 is the amount of money it costs for one student, we multiply that by 120 because there are 120 pupils
£1.50 × 120 = £180
→ £180 is the total cost and now we minus that from the online price of £175
£180 - £175 = £5
