Answer:
The speed of car is 30 miles per hour.
The car traveled 120 miles in 4 hours.
Step-by-step explanation:
We have been given that a car is traveling at a speed of 44 feet per second. We are asked to find car's speed in miles per hour.
[tex]\frac{\text{44 ft}}{\text{ second}}[/tex]
We know 1 mile equals 5280 feet.
[tex]\frac{\text{44 ft}}{\text{ second}}\times \frac{1\text{ mile}}{\text{5280 ft}}[/tex]
We know that 1 hour equal 3600 seconds.
[tex]\frac{\text{44 ft}}{\text{ second}}\times \frac{1\text{ mile}}{\text{5280 ft}}\times \frac{3600\text{ seconds}}{\text{1 hour}}[/tex]
[tex]\frac{44\text{ mile}}{5280}\times \frac{3600}{\text{ hour}}[/tex]
[tex]\frac{158400\text{ mile}}{5280\text{ hour}}[/tex]
[tex]\frac{30\text{ mile}}{\text{ hour}}[/tex]
Therefore, the speed of car is 30 miles per hour.
To find the distance traveled by car in 4 hours, we will multiply 4 by 30.
[tex]\text{Distance traveled by car in 4 hours}=\text{ 4 hours}\times \frac{\text{30 miles}}{\text{hour}}[/tex]
[tex]\text{Distance traveled by car in 4 hours}=4\times\text{30 miles}[/tex]
[tex]\text{Distance traveled by car in 4 hours}=\text{120 miles}[/tex]
Therefore, the car traveled 120 miles in 4 hours.
