In a 25-yard pool, 40 lengths (or 20 laps) equals 1000 yards.
alice's car is 18 feet long. What is the length in yards
If each lap is 25 yards you must swim 70.4 laps to reach one mile.
17+17+10+10=54 yards
10+10+10+10=40 yards
440 divided by 25 = 17.6 so if you swum 18 lengths you would have swum 450 yards.
About 30 yards.
1.68 + 1.5 + 1.26 = 4.44. To the nearest yard, this is 4 yards but that would be of little use. He needs 5 yards, and the question should refer to the least number of whole yards rather than the "nearest yard".
I presume this means the pool is 22 yards long and a lap is to swim from one end to the other and back, for a total of 44 yards. So we divide 800 by 44 and get about 18.18. So 18 laps and about two fifths of the way across the pool. To be exact, 18 laps and 8 more yards.
Typically, short-course pools are 25 yds. long, so a 200 yd. swim would be 4 lengths.
20 yards (3 feet make up a yard)
