Answer:
4t miles per hour
Step-by-step explanation:
Distance refers to the amount of space an object can cover within a period of time. It can be calculated by multiplying speed and time.
Distance= speed × time
Speed is the rate of movement of an object from one place to another.
Speed= Distance/Time.
Time= distance/speed.
If Katie walks at the rate of 4miles per hour.
Her total distance in the hours is d
Total distance= speed× time
Her speed=4miles per hour
Time= t
Katie's total distance=4 miles per hour× t
=4t miles per hour
