Arunner is training for half marathon her training schedule as shown in the table graph and label the unit rates for each day on the number line which day did she run the fastest

Unit Rates: Monday- 9.5 Tuesday- 12 Wednesday- 9.25 Thursday- 10.5 Friday- 11.5

All You Have To Do Was Divide.. The Answer Is Wednesday

  Day          Distance       Time        Rate

Tuesday          4                 38           9.5

Wednesday    6                 72            12

Thursday        4                 37           9.25

Saturday         3               31.5          10.5

Sunday           12              138           11.5

On Thursday, she ran 1 mile in 9.25 minutes, which is the fastest speed.

Step-by-step explanation:

Consider the provided table.

We need to find the unit rate.

Unit rate is the time taken to run one mile. Here the unit rate is the number of minutes divided by the number of miles for each day.

Consider the table:

For Tuesday:

Distance is 4 miles and time is 38 minutes

The unit rate is: 38 ÷ 4 = 9.5 minutes to run one mile

For Wednesday:

Distance is 6 miles and time is 72 minutes

The unit rate is: 72 ÷ 6 = 12 minutes to run one mile

For Thursday:

Distance is 4 miles and time is 37 minutes

The unit rate is: 37 ÷ 4 = 9.25 minutes to run one mile

For Saturday:

Distance is 3 miles and time is 31.5 minutes

The unit rate is: 31.5 ÷ 3 = 10.5 minutes to run one mile

For Sunday:

Distance is 12 miles and time is 138 minutes

The unit rate is: 138 ÷ 12 = 11.5 minutes to run one mile

On Thursday, she ran 1 mile in 9.25 minutes, which is the fastest speed.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
