Answer:
3 km per minute
Step-by-step explanation:
speed = distance / time
315km/105 minutes
= 3 km per minute
(13 + x)/(50 - x ) = (2/1)
Cross Multiply
2(50-x) = 1(13 + x)
100 - 2x = 13 + x
add 2x to both sides
100 -2x + 2x = 13 + x + 2x
100 = 13 + 3x
Subtract 13 from both sides
100 - 13 = 13 - 13 + 3x
87 = 3x
divide both sides by 3
29 = x
(13 + 29)/(50-29) = 42/21 = 2 to 1 ratio
Answer:
Step-by-step explanation:
<u>Multiply both sides by 7:</u>
<u>Subtract 4 from both sides:</u>
<u>Divide both sides by 10:</u>
