Answer:

a 56.25 minutes

b  9.6 miles

Step-by-step explanation:

To find the rate, we take the miles and divide by the minutes

rate = 8 miles / 50 minutes

       .16 miles per minute

A.  how long to run 9 miles

We want to use the formula

d =rt where d is the distance, rate is the rate and t is the time

9 = .16 *t

Divide each side by .16

9/.16 = .16/16 *t

56.25 = t

It will take 56.25 minutes

B  We have a time of 1 hour

We want to use the formula

d =rt where d is the distance, rate is the rate and t is the time

t = 1 hour, but our rate is in minutes

1 hour = 60 minutes so t = 60 minutes

d = .16 * 60

d =9.6 miles

I cannot understand this can you guys help
igor_vitrenko [27]
The mean is not the same thing as median
mean=78+81+85+87=331
mean=331/4=82.75
median is the middle number, but you have a par set of numbers, so your median will be the middle numbers 78,81,85,87 , which are 81+85=166, 166/2=83
83 is your median

<h3>What is division?</h3>

The division means the separation of something into different parts, sharing of something among different people, places, etc.

The expressions are 2.5 × 10⁻³ and 7.1 × 10⁶.

We have to divide 2.5 × 10⁻³ from 7.1 × 10⁶.

\dfrac{2. 5 * 10^{-3} }{ 7. 1 * 10^6}\\\\3.5211 * 10 ^{-10}

The value of the expressions (2.5 × 10⁻³) and (7.1 × 10⁶) in scientific notation is 3.5211 × 10⁻¹⁰. Then the correct option is B.
