To find out when Deepak and his wife will meet for the first time, we need to calculate the time it takes for the sum of the distances they cover to equal the circumference of the track.

First, let's convert their speeds from km/hr to m/min, as the track's circumference is given in meters and we are interested in finding the time in minutes.

Deepak's speed: 20 km/hr = 20,000 meters/hr = (20,000 meters/hr) / (60 min/hr) = 333.33 meters/min
His wife's speed: 13 km/hr = 13,000 meters/hr = (13,000 meters/hr) / (60 min/hr) = 216.67 meters/min

Now, let's add their speeds to find out how fast they are moving towards each other.

Combined speed = Deepak's speed + His wife's speed
Combined speed = 333.33 meters/min + 216.67 meters/min
Combined speed = 550 meters/min

Now, we'll use the combined speed to find out how long it will take for them to meet for the first time.

Time = Distance / Speed
Time = Circumference of the track / Combined speed
Time = 1000 meters / 550 meters/min
Time ≈ 1.81818 minutes

So, Deepak and his wife will meet for the first time in approximately 1.82 minutes.
