Question

A swimming pool is 25 m long and 12 m wide. A single 4 m wide lane is roped off.
Ismaeel swims in the 4 m wide lane. Swimming two
lengths of the pool counts as one lap for Ismaeel.
Kosha swims on the other side of the roped off lane,
in the larger rectangular portion of the pool. A lap
for Kosha consists of swimming once around a circuit
that is 1
2 m away from each edge and 1
2 m away from
the rope divider.
a) How much longer is Kosha’s lap than Ismaeel’s
lap?
b) Ismaeel and Kosha each complete ten laps.
Determine how much farther than Ismaeel that
Kosha swam.

Answer 1

Step-by-step explanation:

Given A swimming pool is 25 m long and 12 m wide. A single 4 m wide lane is roped off. Ismaeel swims in the 4 m wide lane. Swimming two

lengths of the pool counts as one lap for Ismaeel.  Kosha swims on the other side of the roped off lane, in the larger rectangular portion of the pool. A lap for Kosha consists of swimming once around a circuit  that is 1 /2 m away from each edge and 1 /2 m away from  the rope divider.

• Given In a swimming pool the width which is rectangular will be 12 m – 4 m = 8 m. Now Kosha swims around a rectangle ½ m from the edges.
• So we get 8 – ½ - 1/2 m wide
•             = 7 m wide
• Now length will be 25 – 1/2 – 1/2  
•            = 24 m length
• So total distance Kosha is able to swim in one lap will be 24 + 7 + 24 + 7 = 62 m
• So total distance Ismaeel swims in one lap will be 25 + 25 = 50 m (2 lengths)
• Therefore Kosha’s lap will be 62 – 50 = 12m
• Therefore Kosha’s lap is 12 m longer than Ismaeel lap.
• Now In one lap Kosha swims 62 m
• So in 10 laps Kosha will be able to swim 62 x 10 = 620 m
• Now in one lap Ismaeel swims 50 m
• So in each lap Kosha is able to swim 12 m further
• Therefore in 10 laps she is able to swim 10 x 12 = 120 m further.
