Minutes lost hourly is x/y.
One week has 24 * 7 = 168 hours.
168x / y would be minutes lost weekly, and (168/60) (x / y) = (42/15)(x/y) would be hours lost weekly.

Answer:

10080y/x hours

Explanation:

The rate = x/y

x is in minutes

y is in hours.

How many hours will it lose in one week.

Converting one week to minutes.

One week has 7 days: a day has 24 hours.

In one week we have 24×7= 168 hours

60 minutes make one hour : in 168 hours we have

60×168=10080 minutes

Hours lost at the same rate = total minutes/ rate

= 10080/(x/y)

Hours lost= 10080y/x hours

ArbitrLikvidat [17]

The projected population size in 2030 will be : ≈ 44159

First step : determine the population growth rate

Gr = change in population / time

    = ( 1500 - 1100 ) / 1 year

    = 400 = 36%

<h3>Determine the projected population size </h3>

applying Malthus's population projection.

Pp = P₁ ( 1 + r )ⁿ

where ; P₁ = 1500, r = 0.36 , n = ( 2030 - 2019 ) = 11 years

Pp = 1500 ( 1 + 0.36 )¹¹

    = 1500 ( 29.439 )

    = 44158.5  ≈ 44159

Hence we can conclude that the projected population size as at 2030 is 44159
