Question

S The distance bewteen Harry and Kate is 2500 meters. Kate and Harry start walking toward one another

and kate'dog start running baok and forth between Harry aid Kate at a speed of 120 meters per minute.
Harry walks at the speed of 40 meters per minute while Kate walks at the speed of 60 meters per minute.
What distance will the dog have travelled when Harry and Kate meet each other?

Answer 1

Step-by-step explanation:

Let's first find out how much time it takes for Harry and Kate to meet each other:

We can use the formula: distance = speed × time

Let's assume they meet after t minutes.

Distance covered by Harry in t minutes = 40t

Distance covered by Kate in t minutes = 60t

Total distance covered = 40t + 60t = 100t

Since they started from a distance of 2500 meters, the total distance covered is also equal to 2500 meters.

Therefore, we have the equation: 100t = 2500

Solving for t, we get t = 25 minutes.

Now, let's find the distance covered by the dog in 25 minutes.

The dog covers a distance of 120 meters per minute, so in 25 minutes, the dog would cover a distance of:

120 × 25 = 3000 meters

Therefore, the dog would have travelled a distance of 3000 meters when Harry and Kate meet each other.
