Before the start of the car race, Tony Stewart and Jamie Mcmurray have the same amount of fuel in the car. With this fuel Tony Stewart can drive for 4 hours while Jamie can drive five hours. After a time they realize that amount of fuel left in Tony car is 1/4th of the fuel in Jamie car. For long they are racing ?
5/6 hours
Explanation : Let's call the amount of fuel in each car as "x". Tony Stewart's car can drive for 4 hours with x amount of fuel, so his fuel consumption rate is x/4. Jamie Mcmurray's car can drive for 5 hours with x amount of fuel, so his fuel consumption rate is x/5. After a certain amount of time, they realize that the amount of fuel in Tony's car is 1/4th of the fuel in Jamie's car. So, x/4 = x/5 * 1/4. Solving for x, we get x = 20. So the amount of fuel in each car is 20. Now, we can use the fuel consumption rate of each car to find out how long they have been racing. Let's call the time they have been racing as "t". Tony's car has x - x/4 * t = 20 - 20/4 * t = 20 - 5t amount of fuel left. And Jamie's car has x - x/5 * t = 20 - 20/5 * t = 20 - 4t amount of fuel left. We know that Tony's car has 1/4th of the fuel left in Jamie's car, so: 20 - 5t = (1/4) * (20 - 4t) Expanding and simplifying, we get: 20 - 5t = 5 - t 25 - 6t = 5 t = 5/6 hours. So, they have been racing for 5/6 hours.
Can you solve the equation by finding the value of A) Horse B) Cowboy Boot C) Horse Shoe
Horse = 10, Cowboy Boot = 1 ,Horse Shoe= 2
Explanation : Horse = 10, Cowboy Boot = 1 ,Horse Shoe= 2 = Step 1 = 3 Horse = 30 = Horse = 10 .....(A) = Step 2 = 1 Horse + 2 Horse Shoe + 2 Horse Shoe = 18 10 + 4 Horse Shoe =18 HorseShoe = 2 .....(C) = Step 3 = 2 Horse Shoe - 2 Cowboy Boot = 2 4 - 2 Cowboy Boot = 2 = Cowboy Boot = 1 ... (B) = Step4 = Cowboy Boot + Horse * Horse Shoe = 1+10*2 = 21

Explanation : Lena Dunham : 2 , Allison Williams : 5 and Jemima Kirke : 7 Age diff : 7-2 is 5 , 7-5 is 2 and 5-2 is 3 which all are prime numbers
1000 + 40 + 1000 + 30 + 1000 + 20 + 1000 + 10 = ?
Explanation : 4100. 1000 + 40 = 1040 1040 + 1000 = 2040 2040 + 30 = 2070 2070 + 1000 = 3070 3070 + 20 = 3090 3090 + 1000 = 4090 4090 + 10 = 4100
