How to find pool width with just by time and speed?

Calculate width by using time speed and the method you use will depend on what information you already have.Calculate speed, distance or time using the formula d = st,.

To solve for distance use the formula for distance d = st, or distance equals speed times time.

distance = speed x time

Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.

distance = rate x time

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.

speed = distance/time

To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

time = distance/speed

To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

FORMULAS FOR POOL CAPACITY
L = length W = width V = volume D = depth
r = radius (half of the diameter of a circle)
π = (pi) 3.14 (a factor used in calculations with circles)
SURFACE AREA
Rectangular pool = L x W
Circular pool = r² x π
Right triangle = (L x W) ÷ 2
AVERAGE DEPTH
For constant slope: [D (minimum) + D (maximum)] ÷ 2 = AVERAGE DEPTH
Note: For multi-depth pools calculate the volume in sections of constant slope and
add them together.
CUBIC FEET OF VOLUME (surface area times average depth)
Rectangular pool V = L x W x D
Circular pool V = r² x π x D
POOL GALLONAGE IN CUBIC FEET (cubic foot of water = 7.5 gallons)
Rectangular pool gallons = L x W x D x 7.5
Circular pool gallons = r² x π x D x 7.5
FLOW RATE/TURNOVER RATES
SPAS: Required turnover every 30 minutes therefore required flow rate is:
Gallons ÷ 30 minutes = minimum (min) flow rate in gallons per minute (gpm)
LIMITED USE POOLS: Required turnover at least every 8 hours (8 x 60 min = 480 min)
Gallons ÷ 480 minutes = min flow rate in gpm

alculating the average speed is simple using the formula {\displaystyle {\text{speed}}={\frac {\text{distance}}{\text{time}}}}. But sometimes you are given two different speeds used for some periods of time, or over some distances. In these instances, other formulas exist for calculating the average speed
