2 answers:

7 0

6 minutes because 28/8 is 3.5 that is the number of photos that the printer prints in one minute so you / 21 into 3.5 and that is 6 minutes

First you have to divide 28 by 8 to find the amount per 1 minute.
Which equals 3.5 photos per minutes.

Then you have to divide 21 by the photos per minute.

Which gives you your answer; It takes 6 minutes to print 21 more photos

Andre ran 2 kilometers in 15 minutes, and Jada ran 3 kilometers in 20 minutes. Both ran at a constant speed. Did they run at the

Goshia [24]

Answer:

speed of Jada = 6km per hour which is not equal to

speed of Andre = 8km per hour

They did not run at same speed

Step-by-step explanation:

formula of speed = distance covered/ time taken

For Andre

Distance = 2 KM

time = 15 mins

60 mins = 1 hour

15 mins = 1/60 * 15 hour = 0.25 hours

thus,

speed = 2km/0.25 hour = 8 km per hour

Similarly for Jada

Distance = 3 KM

time = 20 mins

60 mins = 1 hour

20 mins = 1/60 * 20 hour = 1/3 hours

thus,

speed = 2km/(1/3)hour = 6 km per hour

Now we have

speed of Jada = 6km per hour which is not equal to

speed of Andre = 8km per hour
