<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
Time required to complete the round trip where x is average velocity on the outgoing trip.
Answer:
7,470
Step-by-step explanation:
<u>Step 1: Convert all into inches</u>
1 feet = 12 inches
2 feet = x inches
<em>Cross multiply</em>
x = 24 inches
1 yard = 36 inches
13 yard = x inches
<em>Cross multiply</em>
x = 468 inches
<u>Step 2: Add all inches together</u>
24 + 468 + 6 = 498 inches
<u>Step 3: Multiply by 15</u>
498 x 15 = 7,470
Therefore, the answer is 7,470.
