We are given a speed of 1.02 mm/hr and we have to convert that speed into inches/day. To find the answer to our problem we can use a 2 steps conversion. First we can convert mm into inches and then the hr into days.
We know that there are 25.4 mm in 1 inch. So let's convert it.
25.4 mm = 1 inch
Speed = 1.02 mm/hr * 1 inch / (25.4 mm) = 0.04016 inch/hr
Speed = 0.04016 inch/hr
Then we know that there are 24 hours in 1 day.
24 hrs = 1 day
Speed = 0.04016 inch/hr * 24 hr/(1 day) = 0.964 inch/day
Speed = 0.964 inch/day
The speed of a slime mold in inches per day is 0.964.
