Answer:
50 minutes = B
Step-by-step explanation:
Andre can run 5 miles in 40 minutes
for 1 miles = 40/5 = 8 minutes
1 mile = 1.61 kilometres
x = 10 kilometres
x= (10x1)/1.61= 10/1.61 = 6.21miles
- for 1 miles = 40/5 = 8 minutes
- 6.21 miles = 8 x 6.21 = 49.689 minutes ≈ 50 minutes = B
Answer:
y = 
Step-by-step explanation:
Given y is inversely proportional to x² then the equation relating them is
y =
← k is the constant of proportion
To find k use an ordered pair from the table
Using x = 3 when y = 1 , then
1 =
=
( multiply both sides by 9 )
9 = k
y =
← equation of proportion
