Answer: C
I think I really hope I’m right!
Step by step explanation:
The ratios that have a unit rate of 5 will be:
6 1/4 kilometers to 1 1/4 minutes.
1 kilometer to 1/5 minutes
1/3 kilometers to 1 2/3 minutes
<h3>How to calculate the value?</h3>
The ratios will be:
1. 6 1/4 to 1 1/4
= 6.25 : 1.25
= 5
2. 4 1/2 to 2
= 4 1/2 / 2
= 2.25
3. 4/5 to 5 minutes
4. 1 kilometer to 1/5 minutes
= 1 : 1/5
= 1 / 0.2
= 5
5. 3 1/10 : 3/10
= 10
6. 1/3 : 1 2/3
= 5
Therefore, the correct options are 1, 4 and 6.

Answer:
The interest will be £45 after 3 years
and £60 after 4 years
Step-by-step explanation:
Principal p = £300, rate r = 5%, time t = 3 year
SI = PRT/100
Interest = (300*5*3)/100
SI = 3*5*3
SI = £45
And after 4 years
Interest = (300*5*4)/100 = 3*5*4
Interest = £60
Answer:
-3.3
Step-by-step explanation:
I had to take a second look because the image and the description wasn't the same, but after simplifying the value, i got -3.3
