Fritzland swam 1/2 miles in 3/4 of an hour . How far can friztland swim in one hour .

Fritland swam a distance of miles in one hour

Explanation:

Given:

Distance being swam, d =

Time, t =

Distance travelled in 1 hour = ?

Distance travelled in is

Distance travelled in 1 hour =

                                              =

Therefore, Fritland swam a distance of miles in one hour

answer is  

a.

p = 78

step-by-step explanation:

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
