A small submarine travels at a speed of 2.4 km per hour. How far will the submarine travel in 0.25 hours
2 answers:
Answer:
Step-by-step explanation:
Distance (how far the submarine travelled) can be found by multiplying the speed by the time.
The speed is 2.4 kilometers per hour.
The time is 0.25 hours.
Substitute the values into the formula.
Multiply. Note that the hours (hr) will cancel each other out.
The submarine travelled <u>0.6 kilometers</u> in 0.25 hours.

<h3>Attachment</h3>Step-by-step explanation:
Convert to the slope-intercept form (<em>y = mx + b</em>):
<em>divide both sides by 2</em>
We choose any three x values and calculate the y value:
for x = -1
for x = 1
for x = -3
Mark the points on the coordinate plane and draw a line through the given points.
