</span>Johann walked 1.2 feet every second.
Find the total feet that Johann walked for 5 seconds.
First, let’s have the given numbers:
=> 1.2 feet
=> 5 second
he walked 1.2 feet in every 1 second. So simply multiply 1.2 x 5 seconds to get
the total feet that Johann walks.
=> 1.2 feet x 5 seconds
=> 6, Thus, Johan walked 6 feet in 5
seconds.
Unit Rate = 1.2 / ft
Unit rate = 6 feet / 5 seconds</span>
