The total time T (in hours) needed to fly from New York to Los Angeles and back can be modeled by the equation below, where d is

tester [12383]

Answer:

Step-by-step explanation:

There are two distinct issues to address, correct?

1, The overall duration T required to fly from New York to Los Angeles:

Time = Distance/average speed

2, The problem related to the race:

A) The total duration of the race would be:

$t=\frac{0.5}{r} +\frac{22}{15r} + \frac{6}{r+5}$

B) For swimming at an average pace of 2 miles per hour, this means r=2.

Substituting r=2 allows us to calculate the total time needed as follows:

$t=\frac{0.5}{2} +\frac{22}{15*2} + \frac{6}{2+5}= 0.25 + 0.73333+ 0.85714=1.84047$

When rounding the result: 1.84047 hours rounds to 110 minutes
