answer : t= 6d
Kelli is running a mile in gym. She runs at a pace of 6 minutes per mile.
We change the speed to miles per minute
6 minutes per mile = 1/6 miles per minute
d is the distance that Kelli has run and t is the number of minutes passed.
Speed is 1/6 mile per minute
We know the formula distance = speed * time
distance is d, speed is 1/6 and time is t
So the equation becomes
Multiply by 6 on both sides
6d = t
t= 6d
