Chana and Josiah started skating at the same time in the same direction, but Josiah had a head start 10 meters past the starting line. Chana skated 3 meters per second and Josiah skated 2 meters per second. Here's a graph that shows a system of equations for this scenario where x is the number of seconds since Chana and Josiah started skating and y is the distance in meters from the starting line.

A graph with two lines and a point. Line A is labeled y equals 10 plus 2 times x. Line B is labeled y equals 3 times x. Point H is on the intersection of line A and line B.
What does point H represent in this context?

Choose 1

A. Chana's distance from the starting line at a time when she is behind Josiah

B. Josiah's distance from the starting line at a time when he is behind Chana

C. Chana's and Josiah's distance from the starting line at the time when Chana catches up with Josiah

D. Chana's distance from the starting line at a time when she is farther than Josiah

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.
