It takes 40 min for a bus to cover 36 miles. A car travels 1.4 times faster. When will they meet if they started 36 miles apart
sveticcg [70]

<u>Bus:</u>

40 min = 36 miles

1 min = 36 ÷ 40 = 0.9 mile


<u>Car:</u>

1 min = 0.9 x 1.4 = 1.26 miles


<u>Total distance covered by both vehicles in 1 min: </u>

1.26 + 0.9 = 2.16 miles


<u>Time needed for both of them to cover 36km:</u>

36 ÷ 2.16 = 16 2/3 min


Answer: They will meet 16 2/3 mins after they have started.

Given f(x) = the quantity of 2x minus 2 divided by 4, solve for f−1(3).
spin [16.1K]
Given: f(x)=(2x-2)/4
find f^-1(3)?
we need to find the inverse of f(x), so
x=(2y-2)/4
2y-2=4x
y-1=2x
y=2x+1
so, then f^-1(x)=2x+1
f^-1(3)=2(3)+1
=6+1
=7
so, the answer is 7
