Donkey A and Donkey B are walking toward each other on a dirt road. Donkey A starts from the barn, 15 miles away from the meeting point, at 1:00 PM. Donkey B starts from the orchard, 10 miles away from the meeting point, at the same time, 1:00 PM. Donkey A walks at a speed of 3 miles per hour, while Donkey B walks at a speed of 2 miles per hour. At what time will Donkey A and Donkey B collide?

@lilybreaths 27 дней назад

@@wege8409 To determine the time when Donkey A and Donkey B collide, we can use the formula: \[ \text{Time} = \frac{\text{Distance}}{\text{Combined Speed}} \] ### Step 1: Calculate the combined speed - Donkey A's speed: 3 miles per hour - Donkey B's speed: 2 miles per hour - Combined speed: \( 3 \text{ miles per hour} + 2 \text{ miles per hour} = 5 \text{ miles per hour} \) ### Step 2: Calculate the total distance between them - Donkey A starts 15 miles away from the meeting point. - Donkey B starts 10 miles away from the meeting point. - Total distance: \( 15 \text{ miles} + 10 \text{ miles} = 25 \text{ miles} \) ### Step 3: Calculate the time it takes for them to collide \[ \text{Time} = \frac{25 \text{ miles}}{5 \text{ miles per hour}} = 5 \text{ hours} \] ### Step 4: Determine the collision time Since they both start at 1:00 PM, they will collide 5 hours later: \[ 1:00 \text{ PM} + 5 \text{ hours} = 6:00 \text{ PM} \] So, Donkey A and Donkey B will collide at **6:00 PM**.

@lilybreaths 26 дней назад

@@wege8409 Let's break this down step by step: 1. Donkey A starts 15 miles away from the meeting point and walks at 3 miles per hour. To find the time it takes for Donkey A to reach the meeting point, divide the distance by the speed: 15 miles / 3 miles per hour = 5 hours 1. Donkey B starts 10 miles away from the meeting point and walks at 2 miles per hour. To find the time it takes for Donkey B to reach the meeting point, divide the distance by the speed: 10 miles / 2 miles per hour = 5 hours 1. Since both donkeys start at the same time (1:00 PM) and take the same amount of time to reach the meeting point (5 hours), they will collide at: 1:00 PM + 5 hours = 6:00 PM So, Donkey A and Donkey B will collide at 6:00 PM.

I studied all this with great interest while studying in college. But now after 13 years it was very difficult to recollect. So when I go for an interview for the position of a mathematic teacher to answer the trigonometric functions was a difficult task. But this video helped me to remember all the trigonometric functions. It is really helpful for me. Thank you so much.
