Starting at sea level, a submarine descended at a constant rate to a depth of −45 mile relative to sea level in 3 minutes. What was the submarine's depth relative to sea level after the first minute?

I believe the answer is -15 miles

Step-by-step explanation:

I hope i help!

because that’s us why

measurement of the swimming pool is given as = 7 yards 4.79 feet

first we will convert this to yards only.

1 foot = 0.33 yards

so, 4.79 feet = yards

so total yards are = yards

now we will convert this in meters.

1 yard = 0.914 meters

8.580 yards = meters

0.842 m = 0.842*100 = 84.2 cm

this becomes 7 meters and 84.2 cm

hence, the pool is 7 meters and 84.2 cm wide.
