Train A has a speed 20 miles per hour greater than that of train B. If train A travels 200 miles in the same times train B travels 120 miles, what are the speeds of the two trains?

please sa mga nag sagut ng mali dito wag nyo naman sabihan ng ubub kayu nagatong nakahanp sasabiha nyopa ng ubub

5x+10 is the correct one

hope this

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}  

5⋅2  

x

2  

x

​    

=240

=48
