intrastate 70 stretches almost 2 ^ 3 * 5 ^ 2 * 11 miles across the United States. About how many miles long is the interest 70?

marshall27 [118]

(2)^3 * (5)^2 * 11

We use PEMDAS so we have to do the exponents first.

2^3 = 8

5^2 = 25

8 * 25 *11

You then go left to right cause they are all multiplication:

200 *11 = 2200 miles

Sandra normally takes 2 hours to drive from her house to her grandparents' house driving her usual speed. However, on one partic

Rudiy27

Answer:

Her usual driving speed is 38 miles per hour.

Step-by-step explanation:

We know that:

$s = \frac{d}{t}$

In which s is the speed, in miles per hour, d is the distance, in miles, and t is the time, in hours.

We have that:

At speed s, she takes two hours to drive. So

$s = \frac{d}{2}$

$d = 2s$

However, on one particular trip, after 40% of the drive, she had to reduce her speed by 30 miles per hour, driving at this slower speed for the rest of the trip. This particular trip took her 228 minutes.

228 minutes is 3.8 hours. So

$0.4s + 0.6(s - 30) = \frac{d}{3.8}$

$3.8(0.4s + 0.6s - 18) = d$

$3.8s - 68.4 = 2s$

$1.8s = 68.4$

$s = 38$

Her usual driving speed is 38 miles per hour.
