A ship is traveling at 55 mph. If the rate of speed increases 5 mph each hour, how long will it be before the ship is traveling at a rate of 75 mph?

A) 2hours

B) 3hours

C) 4hours

C. 4 hours

Step-by-step explanation:

I know this because it needs to be increased 20 mph more and since it increases 5 mph each hour then it would need to be increased the 5 mph 4 times to reach 75 mph.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
