The positions of two divers from the water's surface after a dive are shown: Julie: −38 feet Sue: −45 feet Which inequality expl

shtirl [24]

Answer:

Julie < 38 feet < Sue < 45 feet

Step-by-step explanation:

We know that Julie is less than 38 feet closer to the water's surface, and also we know that Sue is less than 45 feet from the water's surface but farther than 38 feet, because Julie is closer, so we can write this as the inequality that says, Julies is less than 38 feet, 38 feet is less than Sue's distance who is less than 45 feet from the surface:

Julie < 38 feet < Sue < 45 feet

In t hours the train has traveled s miles. Find the formula for v, the speed of the train (in mph) in terms of t and s. Find the

Finger [1]

Answer:

Speed of the train is 60 mph.

Step-by-step explanation:

Given:

In t hours the train has traveled s miles.

t= 3 hrs

s= 180 miles

W need to find the formula for v, the speed of the train (in mph) in terms of t and s.

Also we need to calculate v.

Now by the definition of speed which is stated below.

"Speed is defined as the distance covered by an object per unit time."

"So, mathematically, speed of train v mph is equal to distance traveled by the train s miles divided by time t hours which it takes to cover the distance."

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

Now Substituting given values of t and s in above equation we get.

v= $v=\frac{180}{3}=60 \ mph$

Speed of the train is 60 mph
