A train travels 120 miles in 1.5 hours. At this rate, how many miles can it travel in 5 hours?

 400 miles

Here's one approach to solving

We can form a proportion like so

(120 miles)/(1.5 hours) = (x miles)/(5 hours)

120/1.5 = x/5

120*5 = 1.5*x cross multiply

600 = 1.5x

1.5x = 600

x = 600/1.5

x = 400

Another approach:

Use the formula

speed = distance/time

to find the train's speed is 120/1.5 = 80 mph

Then we can say,

distance = rate*time

distance = 80*5

distance = 400 miles

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
