Answer:
6 hours ;
30351, 30153, 7581, - 7581, - 30153 ;
24°C ;
301
Explanation:
Question(1) isn't well formatted and thus difficult to understand what the poster meant.
2.) Question 2 isn't well formated too; However, it could be observed that, we are required to calculate time taken :
Speed = 80 km/hr ; Distance traveled = 480 km
Time taken = Distance / speed
Time taken = 480 km / 80 km/hr
Time taken = 6 hours
3.)
Given the integers : 30153 ; -30153 ; -7581 ; 7581 ; 30351
Arranging in descending order ; from highest to lowest :
30351, 30153, 7581, - 7581, - 30153
3.)
Temperature in the morning = - 3°C
Temperature in the afternoon = 21°C
Temperature change :
Afternoon temperature - morning temperature
21°C - (-3°C) = 21°C + 3°C = 24°C
4.)
Let the numbers be x and y
x + y = - 234
If x = 67 ; y =?
67 + y = - 234
y = - 234 - 67
y = - 301
