167/308 seconds ≈ 1.22 seconds.

1 hour = 3600 seconds

1 miles = 5280 feet

⇒ 28 miles = 28 x 5280 feet

= 147840 feet

⇒ mph = 147840 feet ÷ 1 hour

= 147840 ÷ 3600 feet/second

= 616/15 ft/s

time = distance ÷ speed

= 50 feet ÷ 28 mph

= 50 feet ÷ (616/15 ft/s)

= 375/308 seconds

≈ 1.22 seconds
