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
