A Lion in a cage walks back and forth sixty feet per minute

A Lion in a cage walks back and forth, sixty feet per minute, seeking a way out of the cage. It took nearly four centuries to find the door. Now, with modem equipment, he is walking three thousand feet per minute and he has three thousand miles by two thousand miles to go yet How long will it take him to cover this territory of said, three thousand by two thousand miles, at the above walking rate?

Solution

1 miles =5260 feet

3000 miles/2000 thousands mile=3/2 miles=3/2*5260 feet=7890 feet

time to cover this territory=7890/3000=2.63 minutes
