Answer:
90 seconds
Step-by-step explanation:
To find the time it takes to take a certain amount of steps, divide the given rate by the time.
3/2 = 1.5
This means she takes 1.5 steps every second. Now, we can multiply this rate by 60 to find how far she will go in that time.
1.5 · 60 = 90
Bethany takes 90 steps in 60 seconds.
