18*60=1080 feet per min
18 times 60 (seconds in a minute) = 1,080 feet in 1 min
Leonardo can travel 1,080 feet in one minute, as he skateboards at a speed of 18 feet per second. This is calculated by multiplying his speed by the total seconds in a minute (60 seconds). Thus, the formula used is distance = speed × time.
