6th grade math, help pleasee:)

a) v=12 feet

b) 1: 12

2: 24

3: 36

4: 48

Step-by-step explanation:

A) v=d/t

They give you 60 feet, which can be plugged in for d (distance), and 5 seconds which can be plugged into t (time).

So, v=60/5=12

B) Kendall runs 12 feet per second, so in the chart:

1 sec x 12 feet = 12 feet

2 sec x 12 feet = 24 feet

3 sec x 12 feet = 36 feet

4 sec x 12 feet = 48 feet

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
