Distance swam in 5 minutes = 85.4 yards
Since, 1 min = 60 seconds and 1 yard = 0.91 meter
5 minutes = seconds
85.4 yards = meters
So, Distance swam in 300 seconds = 77.7 meters
Now, we will use unitary method to determine the distance swam in 70 seconds.
Distance swam in 1 second = = 0.26 meter
So, Distance swam in 70 seconds =
= 18.2 meters
Therefore, the swimmer took 70 seconds to cover the distance of 18.2 meters.
Answer:
Step-by-step explanation:
we know that
The diameter divide a circle into two equal parts
so
The measure of arc FAC is equal to 180 degrees (Remember that a complete circle subtends a central angle of 360 degrees)
we have that
---> given problem
----> by central angle
----> given problem
so
therefore
----> by angle addition postulate
substitute
