Answer:
122.5 minutes
Step-by-step explanation:
21 hotdigs in 6 min
1 hotdog 3.5 minutes
therefore 35 hotdogs = 122.5 minutes
Answer:
2 miles
Step-by-step explanation:
Their combined speed (speed of closure) is 80 mph + 40 mph = 120 mph.
120 mi/h = 120 mi/(60 min) = 2 mi/min
The distance between the trains at the 1-minute mark is ...
(1 min) · (2 mi/min) = 2 mi
They were warned when two miles apart.
Answer:
<h3>Given</h3>
- g varies jointly with h and j
- g = 4 when h = 1/2, j = 1/3
<h3>To find</h3>
- Value of g when h = 2 and j = 3
<h3>Joint variation:</h3>
- g = khj, where k- coefficient
Use given values of h and j, and find the value of k:
- 4 = k*(1/2)(1/3)
- 4 = (1/6)k
- k = 4*6
- k = 24
The equation is now:
Find the value of g when h is 2 and j is 3:
<u>Correct choice</u> is D
