Given:Distance moved =100m=100/1000=0.1kmtime=15min=15/60=0.25hrFormula:Average Speed= Total Distance/Total Time = 0.1/0.25=0.4 Km/hrTherefore the average speed of tortoise is 0.4km/hr

The Average Speed of the Tortoise

To calculate the average speed of the tortoise, we need to convert the given distance and time into the appropriate units. Let's break down the calculation step by step.

Step 1: Convert Distance to Kilometers
The given distance is 100 meters. To convert it to kilometers, we divide it by 1000 (since there are 1000 meters in a kilometer).

100 meters ÷ 1000 = 0.1 kilometers

Therefore, the distance covered by the tortoise is 0.1 kilometers.

Step 2: Convert Time to Hours
The given time is 15 minutes. To convert it to hours, we divide it by 60 (since there are 60 minutes in an hour).

15 minutes ÷ 60 = 0.25 hours

Therefore, the time taken by the tortoise is 0.25 hours.

Step 3: Calculate Average Speed
Average speed is defined as the total distance traveled divided by the total time taken. In this case, the total distance is 0.1 kilometers and the total time is 0.25 hours.

Average speed = Total distance ÷ Total time
Average speed = 0.1 kilometers ÷ 0.25 hours

To divide a number by a fraction, we multiply it by the reciprocal of the fraction.

Average speed = 0.1 kilometers × (1 ÷ 0.25 hours)
Average speed = 0.1 kilometers × 4 hours

Step 4: Simplify the Calculation
To simplify the calculation, we multiply the numbers together.

Average speed = 0.4 kilometers per hour

Therefore, the average speed of the tortoise is 0.4 kilometers per hour.

Explanation:
The average speed of an object is the total distance traveled divided by the total time taken. In this case, the tortoise covered a distance of 100 meters in 15 minutes. To calculate the average speed, we converted the distance to kilometers (0.1 km) and the time to hours (0.25 hours). Finally, we divided the distance by the time to find that the average speed of the tortoise is 0.4 kilometers per hour. This means that on average, the tortoise moves at a speed of 0.4 kilometers every hour.
