You drive from your home to a vacation resort 420 miles away. you return on the same highway. the average velocity on the return trip is 15 miles per hour slower than the average velocity on the outgoing trip. express the total time required to complete the round trip, t, as a function of the average velocity on the outgoing trip, x.

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: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
