Ralph Mike at a steady speed during his 8 mile ride. He finished the ride in 4/5 of an hour which fraction represents Ralph’s speed and miles per hour.
Ralph rode for 4/5 of an hour, so he rode for 8 * 4/5 = 32/5 miles.
To find his speed in miles per hour, we divide the distance he rode by the time he rode for:
Speed = (32/5) / (4/5) = (32/5) * (5/4) = 32/4 = 8
So, Ralph's speed is 8 miles per hour.
