Let x = x = be the present age of Lota. It will be 80. (a) Express the horizontal distance d (in miles) that the plane has own as a function of t. Answer: Since the plane is traveling at a constant speed of 350 mi/h and since distance equals rate times time, we have that d(t) = 350t is the horizontal distance function. Z-scores are useful in statistics because they allow compar. 253km c . After travelling for 6 hours, another man starts at the same place as the first man did, following at the rate of 8 km/h. Keep up with the worlds newest programming trends. Okay, let's get on with it. Therefore if we let: Then, assuming the car is traveling at a constant rate of speed the equation would be "d =rt", Then, assuming the car is traveling at a constant rate of speed the equation would be "d 17.27 km. Directions: Read and analyze the text below. When solving these problems, use the relationship rate (speed or velocity) times time equals distance. 97% of Numerade students report better grades. The answers may vary for each student or each group. Alternatively, using the Product Constancy Table from the chapter of percentages. Sonia's Speed = 6 miles per hour A passenger and a freight train start toward each other at the same time from two points 300 kilometres apart. The first, A:Since you have asked multiple questions , we will solve first question for you. Who is earning faster? Motion 11 1.2. For example, suppose a person were to travel 30 km/h for 4 h. To find the total distance, multiply rate times time or (30km/h)(4h) = 120 km. produced at 200 pesos per unit. , please do not put this sign or this kind of sign / thankyou in advance, 12. We are given that it takes 1/2an hour for the This is a time: t = 1/2 We are given that he averages34miles per hour. Therefore if we let: #r# be the rate of speed the car is traveling. This equation shows the relationship between speed, distance travelled and time taken: Speed is distance divided by the time taken. A:We want to find number of units produced such that cost is equal to revenue. The acute angle between the two lines with direction numbers [1, 1, 0] and [2, 1, 2] a. b. Therefore we can substitute 2w for l in the equation for the perimeter giving: p = 2*(2w) + 2w For this problem we are also told the perimeter is 3*13.7 which is 41.1 so we can substitute 41.1 for p . [Jump to exercises] Suppose we have two variables x and y (in most problems the letters will be different, but for now let's use x and y) which are both changing with time. How much is Gigi charging for a cup of lemonade? Upload your study docs or become a Course Hero member to access this document Continue to access Term Fall Professor NoProfessor Tags Distance, Height, International System of Units The distance the car travels in miles is a function of time, t, in hours given by d ( t) = 50 t. Find the inverse function by expressing the time of travel in terms of the distance traveled. The fraction of work done by a man who can finish a job in 5 hours 8. Then the Lota's age in 5 years will be (x+5) (x +5) ages. The fraction of work done by a man who can finish a job in 2 hours, 6. Its average speed for the trip is v avg = distance time = 150 km 3.2 h = 47 km/h. #4, Q:16. A three-digit number whose hundreds digit is half, A. Their rates were 25 and 35 km/h, respectively.
