Answer:

An equation that relates the speeds of the two legs of the trip

$\frac{640}{x-40}+\frac{640}{x}=4$

Explanation:

Given, we have to use x to represent the speed on the second leg

Speed on first leg when increasing your speed by 40 mph will be (x-40)

Distance is given as 640 miles and time is calculated as

$\text { Time }=\frac{\text { Distance travelled }}{\text { speed }}$

According to the question, increasing speed saved four hours

Therefore, the equation that relates the speeds of the two legs of the trip will be

$\frac{640}{x-40}+\frac{640}{x}=4$
