(04.01)The Martinez family walked 3/5 of a mile in 3/8 of an hour. What equation can be used to calculate their unit rate in miles per hour? A. three-fifths over three-eights equals one and three-fifths miles per hour

B. three-eighths over three-fifths equals one and three-fifths miles per hour

C. three-eighths over three-fifths equals five over eight mile per hour

D. three-fifths over three-eights equals five over eight mile per hour

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}
