d. not enough info.

62.5 pounds

Step-by-step explanation:

Given: An astronaut weighs 170 pounds on Earth but only 68 pounds on Mars.

The weight of the rock sample on Mars = 25 pounds

Since the  "Weight of object on Mars"is directly proportional to "Weight of object on Earth".

Hence, the eight of the rock sample on Earth = 62.5 pounds

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.
