Answer:
150 seconds
Step-by-step explanation:
Remember that
To convert miles to feet multiply by 5,280
To convert hours to seconds, multiply by 3,600
step 1
Convert the average rate of miles per hour to feet per second
step 2
Find out how many seconds does the ride take to travel this length of track
we know that
The length of the track is 3,300 ft
so
Divide the total length of the track by the speed
Let the number of rows be x
rows = x
seats in each row = x + 20
total seats = 1344
x (x + 20) = 1344
x^2 + 20x - 1344 = 0
(x + 48)(x - 28) = 0
x = -48 (rejected, answer cannot be negative) or x = 28
Therefore,
x = 28
x + 20 = 48
Check:
Row = 28
Numbers of seat per row = 28 + 20 = 48
28 x 48 = 1344 (Correct)
Ans:There are 48 seats per row
