The men’s world record for swimming 1500.0 m in a long course pool (as of 2007) is 14 min 34.56 s. at this rate, how many seconds would it take to swim 0.600 miles? (1 mi = 1609 m.)
It will take 585.11 seconds for the swimmer to swim in a long course pool. The first step is to convert 0.600 miles into meters. The next step is to convert 14 minutes into seconds and add the result to 35.56 seconds. Then solve for the time using the rate of the swimmer.
140 s. It would take 140 s to swim 0.150 mi
. Step 1. Convert the time to seconds
Time = 14 min × (60 s/1 min) + 34.56 s = 840 s + 34.56 s = 874.56 s
Step 2. Convert miles to metres
Distance = 0.150 mi × (1609.3 m/1 mi) = 241.4 m
Step 3. Calculate the time to swim 241.4 m Time = 241.4 m × (874.56 s/1500 m) = 140 s
(As of 2012, the men’s freestyle record for 1500 m was 14:31.02.)
797.41 s Explanation: 0.850 mile = 1609 x .85 m = 1367.65 m 14 min 34.56 s = 14 x 60 + 34.56 s = 874.56 s Speed of swimming = Distance / time = 1500 / 874.56 = 1.7151 m /s Time to swim a distance of 1367.65 m = Distance / speed = 1367.65 / 1.7151 = 797.41 s
It will take 140.76 seconds to swim 0.150 miles. Explanation: Distance covered by man by swimming for t time= d d = 1500.0 miles t = 14 minutes + 34.56 seconds 1 min = 60 seconds t = 14 × 60 seconds + 34.56 seconds = 874.56 seconds Speed of the man while swimming = S = If the man swims 0.150 miles with the same speed ,then the time taken by him be T. 0.150 miles = 0.150 × 1609.34 m = 241.401 m (1 mile= 1609.34 meters) T = 140.76 seconds It will take 140.76 seconds to swim 0.150 miles.
Answer 7
We must first find the rate taken to cover 1500.0 m within 14 min and 34.56 sec. We can first convert the time into seconds and hence, we have time = 14(60) + 34.56 = 874.56 seconds.
Recall that
rate = distance/ time.
And using the given for the men’s world record, we have
rate = 1500.0 m / 874.56s = 1.715 m/s
Now, to find the time taken to cover 0.350 miles, we can first convert the distance to meters then use the equation given below.
time = distance/rate
where distance is equal to 0.350(1609) = 563.15 m. Hence, we have
time = 563.15 / 1.715 = 328.37 s
From this, we can see that it will takes 328.37 seconds to cover 0.350 miles.
