<h2>
Time required to complete the round trip
where x is average velocity on the outgoing trip.</h2>
Step-by-step explanation:
Let average velocity of outgoing trip = x mph
The average velocity on the return trip is 15 miles per hour slower than the average velocity on the outgoing trip.
Average velocity of return trip = (x-15) mph
Distance to vacation place = 420 miles
Distance to vacation place = Time for outgoing trip x average velocity of outgoing trip
Distance to vacation place = Time for return trip x average velocity of return trip
We have total time T = t₁ + t₂
That is
![T=\frac{420}{x}+\frac{420}{(x-15)}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B420%7D%7Bx%7D%2B%5Cfrac%7B420%7D%7B%28x-15%29%7D)

Answer:
the answer is 4√7
Step-by-step explanation:
Using Pythagoras Thereon
It is 16²+ 4²
= 256+16
= √272
= √16.49
= 4√7
