Explanation Given information: The speed doubles when the mode of transport changes from bus to car, from 20 mi / hr to 40 mi / hr . Calculation: Consider the provided speed for bus, s = 20 As the formula to calculate time, t , for a distance d at a speed of s is, t = d s Let the time taken by car to be t c and the time taken by bus to be t b . Apply the formula to find the time taken to travel a distance d by bus, t b = d 20 Now consider the provided speed for car, s = 40 Apply the formula to find the time taken to travel a distance d by car, t c =

The scatterplot shows the relationship between Marvin's age and the time it took him to run a mile. Running Times 10 12 14 16 18 Age (years) Which statement best describes the relationship between Marvin's age and the time it takes him to run a mile? As Marvin's age increased, the time it took him to run a mile increased. As Marvin's age increased, the time it took him to run a mile decreased. As Marvin's age increased, the time it took him to run a mile remains constant. There is no relationship between Marvin's age and the time it took him to run a mile. ttps://ola3.performancematters.com/ola/ola.jsp?clientCode=Dvahenricocounty# P Type here to search Time to Run a Mile (minutes)

Gas mileage actually varies slightly with the driving speed of a car (as well as with highway vs. city driving). Suppose your car averages 29 miles per gallon on the highway if your average speed is 48 miles per hour, and it averages 26 miles per gallon on the highway if your average speed is 65 miles per hour. Answer parts (a) and (b) below. a. What is the driving time for a 2300-mile trip if you drive at an average speed of 48 miles per hour? What is the driving time at 65 miles per hour? The driving time at 48 miles per hour is hours. (Type an integer or decimal rounded to two decimal places as needed.) The driving time is at 65 miles per hour is (Round to two decimal places as needed.) b. Assume a gasoline price of $4.43 per gallon. What is the gasoline cost for a 2300-mile trip if you drive at an average speed of 48 miles per hour? What is the gasoline cost at 65 miles per hour? The gasoline cost at 48 miles per hour is $ (Round to two decimal places as needed.) hours. The…
