Answer:

  523.6 km

Step-by-step explanation:

Let x represent the distance traveled by train. Then 1020-x is the distance traveled by bus. The travel times are given by the relation ...

  time = distance/speed

Then the total travel time in hours is ...

  x/160 +(1020-x)/105 = 8

  21x +32640 -32x = 26880 . . . . .  multiply by 3360

  5760 = 11x . . . . . . . . . add 11x -26880

  523.6 ≈ x . . . . . . . . . . divide by 11

Aidan traveled about 523.6 km by train.

Samuel consumed 2161 calories of food on​ Monday, 2378 calories on​ Tuesday, and 1841 calories on Wednesday. In order for​ Samue
german
Number of calories consumed on Monday = 2161
Number of Calories consumed on Tuesday = 2378
Number of Calories consumed on Wednesday = 1841
Daily average intake is 2200
Let calories intake on Thursday be X

Now ,

Average = sum of total calories/ number of calories

=> 2200 = 2161+2378+1841+X/4

=> 2200 x 4 = 6377 + X

=> 8800 = 6377 + X

=> X = 8800-6377

=> X = 2423

So Samuel must consume 2423 calories on Thursday
