Question: A can run 10 km in 50 minutes. What is his speed in km/h?

Options:

Correct Answer: 12 km/h

Solution:

Speed = Distance / Time = 10 km / (50/60) hours = 12 km/h.

A can run 10 km in 50 minutes. What is his speed in km/h?

A can run 10 km in 50 minutes. What is his speed in km/h?

Step 1: Identify the distance A can run, which is 10 km.
Step 2: Identify the time it takes A to run that distance, which is 50 minutes.
Step 3: Convert the time from minutes to hours because speed is usually measured in km/h. To do this, divide the minutes by 60 (since there are 60 minutes in an hour). So, 50 minutes = 50/60 hours.
Step 4: Calculate the speed using the formula: Speed = Distance / Time. Plug in the values: Speed = 10 km / (50/60) hours.
Step 5: Simplify the calculation. First, calculate 50/60, which equals 5/6 hours. Then, divide 10 km by 5/6 hours, which is the same as multiplying 10 km by 6/5.
Step 6: Perform the multiplication: 10 * 6 = 60, and then divide by 5: 60 / 5 = 12.
Step 7: Conclude that A's speed is 12 km/h.
