The red car was faster by 11 feet
To make them even so we compare, divide 54 by 2
So,
: 27 feet in 2 seconds
: 38 feet in 2 seconds
Next, subtract
38 - 27 = 11
So, the red car was faster by 11 feet

Julli [10]

Answer:

3/10 of the renaming full pizza has pepperoni

The actual of the half remaining with pepperoni will be 1/2 - 1/5 = 3/10

This means that 3/10 of the remaining full pizza has pepperoni
