A train from Portland, Oregon, to Los Angeles, California, travels at an average speed of 60 miles per hour and covers a distance of 963 miles. Susana is taking the train from Portland to Los Angeles to see her aunt. She needs to arrive at her aunts' house by 8 p. M. It takes 30 minuets to get from the train station to her aunt's house. What time does the train need to leave Portland for Susana to arrive by 8 p. M.

The train need to leave Portland at 03:27 am

Step-by-step explanation:

step 1

Find out how long it takes the train to travel from Portland, Oregon, to Los Angeles, California

Remember that

The speed is equal to divide the distance by the time

so

The time is equal to divide the distance by the speed

Let

s ---> the speed in miles per hour

d ---> the distance in miles

t ---> the time in hours

we have

substitute

step 2

Adds 30 minutes (time it takes to get from the train station to her aunt's house)

Remember that

Convert to minutes

step 3

Remember that

Convert to minutes

Subtract 993 minutes from 1,200 minutes

Convert to hours+minutes

so

therefore

The train need to leave Portland at 03:27 am

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
