His train has been running for 2 1/2 days straight at a constant speed of 4.8 mph. How far has he traveled? Do we need to convert any of the units to solve this problem?

288 miles.

Step-by-step explanation:

Given:

His train has been running for 2 1/2 days.

We have to convert it into hours.

As we know:

1 day = 24 hours

Speed of train = 4.8 miles per hour

Distance traveled by train = ?

Solution:

As we know:

Therefore, the train will travel 288 miles.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
