Valentina knit a total of 44 centimeters of scarf over 11 nights. How many nights will Valentina have to spend knitting in order to knit a total of 60 centimeters of scarf? Solve using unit rates.

15 nights

Step-by-step explanation:

44 cm over 11 nights equals 4 cm per night

let 'n' = number of nights

4n = 60

n = 15

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.

b
