Answer:
6.4 minutes, or 6 minutes and 24 seconds
Step-by-step explanation:
She is running 4 laps, so she is running 1600 meters total. If she runs 250 meters per minute, divide 1600 by 250 to determine how many minutes it will take...
1600/250 = 6.4
Which is 6 minutes + 0.4 minutes
*there are 60 seconds in a minute, so the 0.4 represents 40% of another minute. Multiply 60 by 0.4 to see how many seconds this is...
(0.4)60 = 24 seconds,
So she ran the laps in 6 minutes and 24 seconds
I would say direct because the more gallons of gasoline used, the bigger the cost.

Multiply 4.8 into (20/3), and multiply 16/9 with (1.2b)

Multiply 9 on both sides
19.2b = 32(9)
19.2b = 288 Divide 19.2 on both sides
b = 15
Each person will pay $7 before taxes and tip.
Step-by-step explanation:
Price of salad = $4
Price of two salads = 4*2 =$8
Price of sandwich = $6
As 4 friends ordered sandwiches, therefore,
Price of 4 sandwiches = 6*4 = $24
Price of slice of cake = $3
Total = 2 salads + 4 sandwiches + 1 slice of cake


5 friends will split the bill evenly, therefore,
Bill for one person = 
Bill for one person = 
Each person will pay $7 before taxes and tip.
