Question

Tom owns a lawnmower that uses 1.1 gallons of gasoline in each hour it is used to mow lawns. If Tom mows for 4 hours, how many gallons of gasoline does the lawnmower consume?

a) 3.3 gallons

b) 4.4 gallons

c) 5.5 gallons

d) 6.6 gallons

Answer 1

When Tom mows for 4 hours using a lawnmower that consumes 1.1 gallons of gasoline per hour, he uses a total of 4.4 gallons of gasoline.

Step-by-step explanation:

If Tom owns a lawnmower that uses 1.1 gallons of gasoline each hour it is used, and he mows for 4 hours, the total amount of gasoline consumed can be calculated by multiplying the hourly gasoline usage by the number of hours mowed. Therefore, you would calculate 1.1 gallons/hour × 4 hours, which equals 4.4 gallons of gasoline.

This example demonstrates an application of basic multiplication to solve a real-world problem related to fuel consumption, similar to working out daily energy usage from gasoline or computing the efficiency of a vehicle's fuel economy. Such problems are often encountered in both academic studies and everyday life, making them an essential component of mathematics education.

To find the number of gallons of gasoline the lawnmower consumes, we need to multiply the number of hours it is used by the gallons used per hour. In this case, the lawnmower is used for 4 hours and uses 1.1 gallons of gasoline per hour. So, the total gallons of gasoline consumed by the lawnmower would be 4 multiplied by 1.1, which equals 4.4 gallons.

Therefore, the correct answer is option b) 4.4 gallons.
