Bernardo travels the same distance at 25mph as he does at 50mph. However, since 25mph is only half of 50 mph, he must travel twice as long at 25mph. If you call the time he traveled 50mph "t", then 

<span>t+2t=3 </span>
<span>3t=3 </span>
<span>t=1 </span>

<span>This means he traveled 1 hour at 50mph. In this time, he traveled 50 miles. He traveled the same distance at 25mph, so his total distance was </span>

<span>50miles+50miles=100miles </span>

<span>so the round trip was 100 miles.</span>

Which fee could decrease an investor's return on investment when the investor may not have bought or sold any stock for a signif
goblinko [34]

Answer: Inactivity fee

Step-by-step explanation:

The rest of the options are not given but there can only be one correct answer to this question and that's the answer above.

Brokerages earn a return when they trade financial instruments for investors as they take a commission from this. When an investor has not traded for a while, brokerages don't get to make earnings and will be holding the account with minimal rewards.

To compensate for this, they charge an inactivity fee that will ensure that they get some form of earnings for managing the account and not receiving commission.
