Daniel is rollerblading at 15 miles per hour


Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15


Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15

RUDIKE [14]
In the given question, there are numerous information's already provided. It is important to note then down first. With the help of those given information's the required answer can be easily reached.
Percentage of students that weighed 140 pounds = 75 percent
Then
Percentage of students that weighed more than 140 pounds = (100 - 75) percent
                                                                                                  = 25 percent
Total number of students that were weighed = 40 students
Total number of students that weighed more than 140 pounds = (25/100) * 40
                                                                                                    = (40/4) students
                                                                                                    = 10 students
So the number of students that weighed more than 140 pounds is 10. So the correct option in regards to the given question is option "1".

Rachel runs 6 miles in 50 minutes. At the same rate, how many miles would she run in 35 minutes?
Naily [24]

Answer: 4.2 miles

Step-by-step explanation:

So she ran 6 miles in 50 minutes how long will she run in 35 minutes?

So the equation will therefore be:

6=50

x=35

Cross multiply

6 x 35 = 50x

210 = 50x

Divide both sides by 50

The answer is 4.2 miles
