A = 16 miles per hour
B = 7.5 hours
C = 96 miles
Step by step explanation:
A: If the car travels 56 miles in 3.5 hours you divide the 56 miles by the 3.5 hours and then you will get your unit rate of 16 miles per hour.
B: Now that you know that your unit rate is 16 miles per hour you can figure out how long it will take the car to travel 120 miles. To find this answer all you have to do is divided the amount the car traveled, 120 miles, by the unit rate, 16 miles per hour. After doing the division you will get your answer of 7.5 hours/ 7 hrs and 30 mins.
C: This one is pretty simple. All you have to do is take your unit rate of 16 and multiply it by the 6 hours. After doing your multiplication you will get your answer of 96 miles.
I hope you understand and this answered all of your questions. :)
