A taxi covers 2/5 km in 10 minutes . Find the speed of the car in km/hr

Answer: 2.4 km/hr2.4\text{ km/hr} (or 225 km/hr2\frac{2}{5}\text{ km/hr})

Step-by-step solution

Step 1: Convert time from minutes to hours

Since the speed is required in km/hr\text{km/hr}, convert the given time of 10 minutes10\text{ minutes} into hours. Since 1 hour=60 minutes1\text{ hour} = 60\text{ minutes}, divide 1010 by 6060, which simplifies to 16 hr\frac{1}{6}\text{ hr}.

Step 2: State the formula for speed

Speed is defined as the total distance covered divided by the time taken. Here, the distance is 25 km\frac{2}{5}\text{ km} and time is 16 hr\frac{1}{6}\text{ hr}.

Step 3: Calculate the speed in km/hr

Substitute the distance 25 km\frac{2}{5}\text{ km} and time 16 hr\frac{1}{6}\text{ hr} into the formula. Dividing by a fraction is equivalent to multiplying by its reciprocal: 25×6=125=2.4 km/hr\frac{2}{5} \times 6 = \frac{12}{5} = 2.4\text{ km/hr}.
