Answer:

The answer is Ari, Beth, Cindy

Explanation

Ari

2¾ miles is 2.75 miles
speed of 2½ miles per hour is 2.5 mi/h

DISTANCE = SPEED × TIME

t = d/s

= 2.75/2.5

= 1.1hr

= 66mins

Beth

1¾ miles is 1.75 miles
speed of 1¼ miles per hour is 1.25 mi/h

t = d/s

= 1.75/1.25

=1.4hr

=84mins

Cindy

1hr 21mins is 81mins

Maria walked 3 km west and 4 km south calculate how far she is from her starting point.

Rufina [12.5K]

Answer:

5 km

Step-by-step explanation:

We are given the distances walked by Maria;

3 km west and 4 km south

We are required to determine the displacement from her starting point;

We are going to use Pythagoras's theorem;

a² + b² = c²

Taking, the distances towards south and towards west as the legs of the triangle;

Then, c² = 3² + 4²

= 25

c = √25

= 5 km

Therefore, the displacement from the starting point is 5 km

Yanka [14]

The value of $Q_{1} , Q_{2} ,$ , and $Q_{3}$ of each data is shown in the diagram below

Group A

Mean = $\frac{41+44+45+48+49+50+52+54+55+58}{10} =49.6$
Median = 49.5
Range = $58-41=17$
Interquartile Range = $Q_{3}- Q_{1} =54.5-44.5=10$

Group B
Mean = $\frac{40+41+43+45+48+52+55+57+60+62}{10}=50.3$
Median = 50
Range = 62-40=22
Interquartile range = 58.5-42 = 16.5

Correct statement: the time in Group B has a greater interquartile range
