Upstream speed = (Upstream distance)/(Upstream time) The boat can travel 27 miles upstream in 3 hours Let x be the speed of the boat (without current), let y be the speed of the current. Find the speeds of the boat and the current? Solution: The same boat can travel 30 miles downstream in 2 hours. It takes 3 hours for a boat to travel 27 miles upstream. One number is three times the other number.ĥ. One number is three times the other number.
The second condition is the difference between the numbers is 60.Ĥ. The first condition is the first number is six times the second number. Let the first number be x, the second number be y. The difference between the numbers is 60. The first number is six times the second number. So, costs of one bush is $23, and of one tree is $47.ģ. Subtract equation (iii) from equation (i) The second condition is he bought 6 bushes and 2 trees and totaled $232 The first condition is he bought 13 bushes and 4 trees from the nursery for the first time and its total cost was $487 Let the cost of each bush be x, one tree is y. What were the costs of one bush and of one tree? Solution: The bills do not list the per-item price. For the second time, he bought 6 bushes and 2 trees and totaled $232. Mahesh bought 13 bushes and 4 trees from the nursery for the first time and its total cost was $487. Therefore, the required 2 digit number is 25.Ģ. If the numbers are reversed, then the number can be written as 10y + x The sm of two digits of the number as can be written as 10x + y If the numbers are reversed, then the number is increased by 27. The sum of the digits of a two-digit number is 7. Solution:Īccording to the data provided in the question, When the digits are reversed, the number is increased by 27. Also, have a look at Worksheet on Simultaneous Linear Equations and prepare well for the exam.ġ.
