Answer:
41 ≤ x
x ≤ 45
Step-by-step explanation:
25% = 1/4
1/4(40)
Divide 40 by 4 to remove the 1/4
10
25% of 40 is 10.
in the first half he would have swam 1 km. there are 1000m in a km so 1000/200=5 so he swam the first 200 fly, then a 200 breast, then a 200 fly again, then another 200 breast the finish the first 1 km with a 200 fly. so we switched strokes 4 times.
PS i wouldn't recommend doing a 2 km swim fly and breast
