Express train travel time:
72x = 18
x = 18/72 = 1/4, or 0.25 hours. A quarter of an hour is 15 minutes
x = 15 minutes
Local Train Travel time:
54x = 18
x = 18/54 = 1/3 hour, or 20 minutes
Adding the stops: 1.5 * 6 = 9 additional minutes
Total Travel time: 20 + 9 = 29
Local train takes 29 - 15 = 14 minutes longer.
Answer is 14 minutes
Answer:
it will take 3 hours
Step-by-step explanation:
mom
packages = 6+ 50 *h
dad
packages = 42 + 38h
set them equal
6+50h = 42 + 38h
subtract 38h from each side
6+50h-38h = 42+38h-38h
6+12h = 42
subtract 6 from each side
6-6+12h = 42-6
12h =36
divide by 12
12h/12 = 36/12
h = 3
it will take 3 hours
6: 1,3,2,6
7: 1,7
Factors of 6 are 1,3,2,6 because 1x6 (6x1) and 3x2. (2x3)
Factors of 7 are 1,7 because seven is a odd number so you can only multiply it by one and itself. (1x7 or 7x1)
When x = 0.5, the answer is 0.45
When x = 1.5, the answer is 1.35
