Answer to Problem 41PPE

The number of hours will be given by d60 .

Explanation of Solution

Given:

It is given to suppose that a family drives at an average rate of 60 mi/h on the way to visit relatives and then at an average rate of 40 mi/h on the way back. The return trip takes 1h longer than the trip there.

It is known that

  speed = distancetime

It is given that to assume the distance as d miles traveled to visit their relatives.

Let t1 be the time taken by family to reach their relative place.

Then,

  60= dt1t1=d60

So, the number of hours will be given by d60 .

b)

To determine

To evaluate: the number of hours did it take to make the return trip.

Answer to Problem 41PPE

The number of hours will be given by d40 .

Explanation of Solution

Given:

  18=3(2x6)

Let t2 be the time taken by family in returning from their relative place.

Then,

  40= dt2t2=d40

So, the number of hours will be given by d40 .

c)

To determine

To evaluate: the number of hours did it take to make the return trip.

Answer to Problem 41PPE

The total distance is 120mi and the average is 24 mi / h.

Explanation of Solution

Given:

  18=3(2x6)

It is known that

  speed = distancetime

It is given that to assume the distance as d miles traveled to visit their relatives.

Let t1 be the time taken by family to reach their relative place.

Then,

  60= dt1t1=d60

Let t2 be the time taken by family in returning from their relative place.

Then,

  40= dt2t2=d40

Now, the total time taken will be sum of t1 and t2,

  t=t1+t2=d60+d40

It is given that return trip takes 1 h longer than the trip there,

  t1=t21d60=d401d60=d404023d=d4023dd=40d3=40d=120mi

So the total distance traveled by family is 120mi.

Now,

Average rate for the trip,

Finding the total time taken by the family,

  t=d60+d40=12060+12040=2+3=5h

So,

Average rate,

  =dt=1205=24mi/h

So, the average rate for the entire trip is 24mi / h.
