Get brainiest if right? A freight train was supposed to travel 1300 miles in 50 hours.
When the train went 0.4 of this distance, it was delayed by 4
hours. What should the new speed of the train be to arrive on
time?

30 mph

Step-by-step explanation:

train stopped after 520 miles

780 miles to go

stopped at 20 hours

stopped for 4 hours

34 hours used up...

26 hours left

780 miles to go

780 miles/26 hrs = 30 m/hr

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

if x = 1, then the answer is 3.5
