1. for the swim - a - thon, brandon is going to raise $0.40 for every lap he swims. brandons goal is to raise $36.00. how many laps does he need to swim to meet his goal?

Explanation:

Step1: Calculate number of laps for 350 - meter swim

To find the number of laps for a 350 - meter swim when one lap is 25 meters, we divide the total distance by the distance of one lap. So, $350\div25 = 14$.

Step2: Find the time - difference for the swimmers

To find out how much faster Carly swam, we subtract Carly's time from Ellie's time. So, $37.419 - 32.612=4.807$ seconds.

Step3: Convert length of pool to inches

Given 1 meter is about 40 inches and the length of the pool is 25 meters, we multiply the length in meters by 40. So, $40\times25 = 1000$ inches.

Step4: Calculate width of each lane

The width of the pool is 10 meters and it is divided into 6 lanes. We divide the width of the pool by the number of lanes. So, $10\div6=\frac{10}{6}=\frac{5}{3}\approx1.67$ meters.

Step5: Determine number of laps for fundraising

Brandon raises $0.40 per lap and his goal is $36.00. We divide the goal amount by the amount per lap. So, $36\div0.4 = 90$ laps.

Answer:

1. 14 laps
2. 4.807 seconds
3. 1000 inches
4. $\frac{5}{3}\approx1.67$ meters
5. 90 laps
