If it takes Kathy 2 hours to bake 20 cupcakes, then at that rate, how many cupcakes could be made in 16 hours?

The answer is 160

Step-by-step explanation:

If it takes 2 hours to bake 20 cupcakes, then the rate is:

20 cupcakes in 120 minutes

Which is equal to 1 cupcake in 6 minutes

Therefore, in 16 hours, or in 16*60=960 minutes, the number of cupcakes that could be made can be found using proportion:

Let's denote the number of cupcakes that could be made in 960 minutes as 'x'

Then:

1 cupcake - 6 minutes

x cupcakes - 960 minutes

Find x: x=(960 * 1)/6=160 cupcakes

Thus, the answer is 160

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
