What data is important to a driver?
Which is a greater distance—a mile or a kilometer?
If a sign read “100 miles to the Canadian Border”, would the numeral used to represent the number of kilometers be greater than 100 or less than 100?
Miles--A unit of length equal to 1760 yards
1 mi = Kilometers
The kilometer is unit of length in the metric system equivalent to one thousand meters.
1 Km = miles

A car travels at an average rate of speed of 50 miles per hour (mph) for 6 hours. How far does this car travel? Use the distance formula: D = R * T where D = distance traveled in miles R = rate of speed T = time in hours D = 50 * 6
= 300 miles

Jimmy travels once a month to his grandparent’s home on the coast. He determines that he travels at an average rate of speed of 60 mph for 3.5 hours each way.
How far away do Jimmy’s grandparents live?
D = R * T fill in known variables
How many miles does Jimmy drive in total?
D = R * T = 60 * 3.5 = 150 miles

Jack lives in New York and will be attending college in Atlanta, Georgia. The driving distance between the two cities is 883 miles. Jack knows that the speed limit varies on the roads he will travel from 50 mph to 65 mph. He figures that he will average about 60 mph on his trip. At this average rate, how long will he be driving? (Round to the nearest tenth of an hour) D = R * T 883 / 60 = hrs. & (0.716 * 60 minutes) = 14 hrs., 43 minutes
D / R = T

Danielle drove from Atlanta, Georgia, to Denver, Colorado, which is a distance of 1,401 miles.
If she averaged 58 MPH on her trip, how long is her driving time to the nearest minute?
Use the distance formula and fill in known values.
D = R * T
1401 = 58 * T
1401 / 58 = T
T = = 24 + ( * 60) = 24 hrs., 9 ½ min.

Ruth is planning a 1,543-mile trip to a math teacher’s conference in San Diego. She plans to average 50 MPH.
At that speed, how many hours will she spend in the car? Express to the nearest hour.
Use the distance formula and fill in known values.
1543 = 50 * T
T = 1543/50 = = 31 hrs.

20. EXAMPLE 4
Juan has a hybrid car that averages 40 miles per gallon. His car has a 12-gallon tank.
How far can he travel on one full tank of gas?
Distance = (miles per gallon) * (number of gallons)
Distance = (kilometers per liter) * (number of liters)
D = mpg * gal. OR D = kpl * l
D = 40 * 12 = 480 miles

When Barbara uses her car for business, she must keep accurate records so that she will be reimbursed for her car expenses.
When she started her trip, the odometer read 23, When she ended the trip it read 24, Barbara’s car gets 32 mpg. Her tank was full at the beginning of the trip. When she filled the tank, it cost her $40.10.
What price did she pay per gallon of gas on this fill-up?

start odometer 23,787.8; end odometer 24,108.6
32 mpg; $40.10 to fill her tank
What price did she pay per gallon of gas on this fill-up?
D = mpg * gal.
24,108.6 – 23,787.8 = miles
