Question

Brenda has to remote controlled race cars painted red and blue. The red car travel 38 feet in two seconds. The blue car traveled 54 feet in four seconds. Which car was faster and by how much

Answer 1

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
