Step 1: First, we need to convert the distance from meters to kilometers because the speed is asked in km/hr. We know that 1 km = 1000 m. So, 800 m = 800/1000 = 0.8 km.

Step 2: Next, we need to convert the time from minutes to hours because the speed is asked in km/hr. We know that 1 hour = 60 minutes. So, 6 minutes = 6/60 = 0.1 hours.

Step 3: Now, we can calculate the speed. Speed is defined as the distance travelled per unit of time. So, speed = distance/time = 0.8 km / 0.1 hr = 8 km/hr.

So, the speed of Usha is 8 km/hr.
