Question

Jamar and his family frequently drive from their home in
Riverside, California, to Jamar's grandparents' house in Tucson,
Arizona. Because much of the drive is across the desert, Jamar's
parents are usually able to drive at a constant rate for the entire
trip. Some data about a typical one-way trip are shown below.
Data for a Typical One-Way Trip
The car's gas tank holds 11 gallons of gas.
It takes 2 tank of gas to make of the trip.
The car uses gallon of gas to travel 11} miles.
The car travels 5 miles in 6 minutes.

1. Write a unit rate that describes the number of tanks of gas
required per trip.


2. Write a unit rate that describes how far the car travels per
gallon of gas.

3. Explain how you can determine the total distance of the
one-way trip

4. At what rate, in miles per hour, do Jamar's parents drive?

5. Write a unit rate that describes how long the one-way trip takes in
hours and minutes per trip.

Answer 1

Answer:

1. 1.5 tanks per trip
2. 28 miles per gallon
3. 462 miles per trip
4. 55 miles per hour
5. 8 hours 24 minutes per trip

Step-by-step explanation:

1.

Tanks per trip is found by dividing tanks by trips.

  (1/4 tank)/(1/6 trip) = 6/4 tanks/trip = 3/2 tanks/trip = 1.5 tanks/trip

__

2.

Miles per gallon is found by dividing miles by gallons.

  (11 1/5 miles)/(2/5 gallons) = (56/5 miles)/(2/5 gallons) = 56/2 miles/gallon

  = 28 miles/gallon

__

3.

  distance/trip = (gallons/tank)×(tanks/trip)×(miles/gallon)

  = (11 gallons/tank) × (3/2 tanks/trip) × (28 miles/gallon)

  = (11·3/2·28) miles/trip = 462 miles/trip

__

4.

Speed is found by dividing miles by hours.

  speed = (5.5 miles)/(6/60 hours) = 55 miles/hour

__

5.

The time for a given distance is found by dividing distance by speed.

  time/trip = (miles/trip)/(miles/hour) = (462/55) hours/trip = 8.4 hours/trip

There are 60 minutes in an hour, so 0.4 hours is 0.4·60 minutes = 24 minutes.

A one-way trip takes 8 hours and 24 minutes.
