Answer:
are you working with ratios, rates, and percents?
Step-by-step explanation:
From both sides of the equation, 4 should have been subtracted.
The solution should look like this:
X + 4 = 28
From each side, subtract 4 :
<em>X = 24</em>
I'd like to demonstrate more steps, but the answer has already popped up, so there aren't any more steps.
So speed = distance divided by time, therefore 70 miles divided by 35 minutes = 120mph. The speedboats speed was 120mph.
Hope this helps
