A truck covers a particular distance in 3 hours with the speed of 60 miles per hour. If the speed is increased by 30 miles per h
Scorpion4ik [409]

9514 1404 393

Answer:

  2 hours

Step-by-step explanation:

Time, speed, and distance are related by ...

  d = st

The distance covered is ...

  d = (60 mi/h)(3 h) = 180 mi

Then the time taken at the higher speed is ...

  180 mi = (60 mi/h +30 mi/h)(t)

  t = (180 mi)/(90 mi/h) = 2 h

The time taken at the higher speed is 2 hours.

Help me please me please
saw5 [17]

Answer:

58 cm^2

Explanation:

there are three rectangles in the shape

the first one on the left has length = 7 cm and width = 3 cm.

so area = l × w

= 7×3

=21 cm^2

the one in the middle has length = 4 cm and width = (7- 3) => 4cm

so area = 4 × 4

= 16 cm^2

the last one to the right is identical to the first, so area = 21 cm^2

The combined area = 21 + 16 + 21

= 58 cm^2

JulsSmile [24]

Complete question :

Rae and Doris are training to swim a 200-meter freestyle race. The table lists their practice times during training camp.

Rae’s Times(minutes)-2.12, 2.01, 2.46, 2, 2.22, 2.31, 2.23

doris times(minutes)-2.32, 2.19, 2.26, 2.03, 2.11, 2.14, 2.07

The median of Raes data is(drop down box answers, 2,2.03,2.14,2.22)minutes,and the median of doris data is(drop down box answers, 2,2.03,2.14,2.22)minutes. The interquartile range for rae is(drop down box answers, 0.01,0.13,0.26,0.30), and the interquartile range for doris is(drop down box answers, 0.02,0.06,0.18,0.19). The two data sets overlap(drop down box answers,very little, a lot

Answer:

Rae's median = 2.22

Rae's IQR = 0.30

DORIS median = 2.14

Doris IQR = 0.19

Step-by-step explanation:

Given :

Rae's time :

Ordered data : 2, 2.01, 2.12, 2.22, 2.23, 2.31, 2.46

Median = 1/2(n+1)th term ; n = 7

Median = 1/2(8) = 4th term

Median = 2.22

Q1 = 1/4(8)th term

Q1 = 2nd term = 2.01

Q3 = 3/4(n + 1)th term

Q3 = 3/4(8)th term

Q3 = 6th term = 2.31

Interquartile range = Q3 - Q1 = 2.31 - 2.01 = 0.30

DORIS Data:

Ordered data: 2.03, 2.07, 2.11, 2.14, 2.19, 2.26, 2.32

Median = 1/2(n+1)th term ; n = 7

Median = 1/2(8) = 4th term

Median = 2.14

Q1 = 1/4(8)th term

Q1 = 2nd term = 2.07

Q3 = 3/4(n + 1)th term

Q3 = 3/4(8)th term

Q3 = 6th term = 2.26

Interquartile range = Q3 - Q1 = 2.26 - 2.07 = 0.19
