Answer:
1. 1.5 inches per minute
2. 90 inches per hour
Step-by-step explanation:
speed = 
1. total distance covered =
+ 
= 
= 
= 4
inches
Total time taken =
+ 
= 
= 
= 3 minutes
The ants average speed = 
= 1
= 1.5
The ants speed is 1
inches per minute.
2. Since;
60 minutes = 1 hour
3 minutes = x hours
x = 
= 
= 0.05 hours
Speed = 
= 90 inches per hour
The red ants speed is 90 inches per hour.

Answer:
Is not correct. The product not always will be smaller.
Step-by-step explanation:
A fraction could increase a number if you multiply it.
If the numerator is higher to the denominator, it will increase it.
If the numerator is smaller to the denominator, it will decrease it.
<u>For example,</u>
10 x 4/3
For fraction multiplication, multiply the numerators and then multiply the denominators to get
10×4/1×3=40/3= 13,33
13,33 is higher than 10.
5 x 10/3
For fraction multiplication, multiply the numerators and then multiply the denominators to get
5×10/1×3=50/3
16,66 is higher than 5.
