Given:
An athlete who makes 
laps in 3 mins 45 seconds on a 400m field.
To find:
The speed of the athlete in m/s.
Solution:
We know that,
Distance covered in 1 lap = 400 m
Distance covered in laps = 
m
= 
m
= 
m
We know that,
1 minute = 60 seconds
3 minutes = 180 seconds
3 minutes 45 second = 180 + 45 seconds
= 225 second
The speed of the athlete is:
Therefore, the speed of the athlete is about 8.44 m/s.

Answer:
$1.475 is the average amount of snack sales per ticket sold.
Step-by-step explanation:
We are given the following in the question:
Number of popcorn bags sold = 3
Cost of a popcorn bag = $2.25
Total cost of popcorn bag = 
= $6.75
Number of soda sold = 4
Cost of a soda = $1.50
Total cost of soda = 
= $6.00
Number of candy bars sold = 2
Cost of a candy bar = $1.00
Total cost of candy bars = 
= $2.00
Total sales =
Total cost of popcorn + Total cost of soda + Total cost of candy bar
Average amount of snack sales per ticket sold =
Thus, $1.475 is the average amount of snack sales per ticket sold.
