Answer:

45 miles/hour

Step-by-step explanation:

We need the speed in miles per hour so we need to changes minutes to hours

20 minutes * 1 hour /60 minutes = 1/3 hour

Speed = distance/ time

           = 15 miles/(1/3 hour)

            =15 *3 miles/hour

            = 45 miles /hour

Answer:

The time at which the two trains will meet is 1 hour and 24 minutes

Step-by-step explanation:

The distances between the two trains = 196 miles

The direction of the two trains = Towards each other

The speed of one of the trains = 80 miles per hour

The speed of the other train = 60 miles per hour

Let 't' represent the time at which the two trains meet, we have;

80·t + 60·t = 196

∴ 140·t = 196

t = 196/140 = 7/5

The time at which the two trains will meet, t = 7/5 hours = 1.4 hours = 1 hour, 24 minutes.

A circle with radius 6 has a sector with a central angle of 48 what is the area of the sector
inn [45]

Answer:

≈ 15.08 units²

Step-by-step explanation:

The area (A) of the sector is calculated as

A = area of circle × fraction of circle

   = πr² × \frac{48}{360} ( r is the radius )

   = π × 6² × \frac{48}{360}

   = 36π ×\frac{48}{360} = π × \frac{48}{10} = \frac{48\pi }{10} ≈ 15.08
