Answer:
It takes 0.619 hours (approximately 37 minutes) for the van to catch up with the storm.
They have driven 33.43 miles
They will catch up when their distances are equal.
Step-by-step explanation:
The speed of the van is 54 mph, and the speed of the storm is 33 mph. They are going in the same direction, so the relative speed is the difference of their speeds:
relative speed = 54 - 33 = 21 mph
Now, to find the time when the van reaches the storm, we just need to use the equation:
distance = speed * time
13 = 21 * t
t = 13 / 21 = 0.619 hours
The distance traveled by the van is:
distance = 54 * 0.619 = 33.43 miles
The van will catch up when the distances are equal (the distance of the storm is 13 + 33*0.619 = 33.43 miles)
Answer:
The numbers are 12 and 36
Step-by-step explanation:
x + y = 48
x - y = 24
Add y to both sides of the equation
x = 24 + y
Substitute new value for x into first equation
24 + y + y = 48
Add y's together
24 + 2y = 48
Subtract 24 from both sides of the equation
2y = 24
Divide both sides of the equation by 2
y = 12
48 - 12 = 36
The numbers are 12 and 36
Hope this helps :)
Answer:
-7
Step-by-step explanation:
*Two negatives will cancel out and turn into addition.
-12 - (-5)
Subtract 12 from 5 and add the negative sign:
-12 + 5 =
-7
The answer would be -7
Hope this helped.
