Q..If you run a 10-kilometer race in 43 minutes 30 seconds, calculate your average time per mile and
your average speed in miles per hour using Python
Calculator. (Hint: there are 1.61 kilometers in a mile)

# Define the distance of the race in kilometers and the time taken in minutes
distance_km = 10
time_minutes = 43 + 30 / 60

# Convert distance from kilometers to miles
distance_miles = distance_km / 1.61

# Calculate average time per mile
time_per_mile = time_minutes / distance_miles

# Calculate average speed in miles per hour
speed_mph = distance_miles / (time_minutes / 60)

# Output the results
print("Average time per mile:", round(time_per_mile, 2), "minutes")
print("Average speed:", round(speed_mph, 2), "miles per hour")
