Choose what you think the expressions below best represent within the context of the word problem. a man traveled a certain number of miles by automobile and then nine times as far by airplane. his total trip was 600 miles in length. how far did he travel by plane?

540 miles

Step-by-step explanation:

Let the number of times he travelled by automobile be T. If he travels a certain number of miles by automobile and then nine times as far by airplane, then the number of miles by airplane would be

= 9T

If his  total trip was 600 miles in length then

T + 9T = 600

10T = 600

T = 60

By plane, he must have traveled

= 9 * 60 miles

= 540 miles

ian gonna lie that is way to much

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
