A car travels 500 miles on 16 US gallons of fuel What is its fuel efficiency m kilometer per liter? Do not conv engineering notation. Every 10 seconds a very generous person gives you 1 cent. How much money in dollars will you have alter year? Do not convert to engineering notation. A rectangular room, is 20 fee. wide and 30 feet, long. What is the area in square meters? A car is traveling at 100 miles per hour. How long (in seconds) does it take for the car to travel 100 feet?

Solution

Q17)

Distance = 500 miles

Conversion Factor: 1 mile = 1.6093 km

Distance(in Km) = 500 miles * 1.6093 km/mile = 804.672 Km

Fuel = 16 Gallons

Conversion Factor: 1 gallons = 3.78541 L

Fuel in Liters = 16 * 3.78541 = 60.5666 L

Fuel Efficiency = 804.672 Km/60.5666 L = 13.285 Km/L

Q18)

1 year = 365 days = 365 * 24 hours = 365 * 24 * 60 minutes = 365 * 24 * 60 * 60 seconds = 31536000 seconds

In 10 seconds, we will get 1 cent

Money in 1 year = 3153600 cents = 31536$

Q19)

Area = Length * Breadth

=> 20 feet wide * 30 feet long

=> 600 ft^2

1 ft^2 = 0.092093 m^2

Hence area in (m^2) = 55.7418 m^2

Q20)

1 feet = 0.3048m

Distance = 100 feet = 30.48m = 0.018939394 miles

Time taken = Distance/Speed = 0.018939394 miles/100 miles/hr = 0.68184 seconds
