Nash is training for a marathon and decides to train for 26 miles every week. In the first week, the ratio of the number of miles he ran to the number of miles he walked 3:10. In the fifth week the ration ran to walked is 8:5. How many miles did nash run in week 5

Answers

Answer:

16 miles

Step-by-step explanation:

From the question given above, the following data were obtained:

Miles per week for training = 26 miles.

In the 5th week:

Ratio of miles ran to miles Walked is 8:5

Thus, we can obtain the miles ran by Nash in the 5th week as follow:

Ratio ran = 8

Ratio walked = 5

Total ratio = 8 + 5 = 13

Miles per week for training = 26 mile

Mile ran in the 5th week = 8/13 × 26

Mile ran in the 5th week = 8 × 2

Mile ran in the 5th week = 16 miles

Therefore, Nash ran 16 miles in the 5th week of training.

The summit of a mountain pass is 8,050 ft above sea level. the valley below is 12 and 1/2 ft below sea level. what is the vertical distance between the summit and the valley

please please help me ​

Answers

Answer:

Vertical distance between the valley and the summit = 8062.5 ft

Step-by-step explanation:

Distances above the sea level are denoted by positive notations and below the sea level by negative notation.

Summit of a mountain pass = 8050 (above the sea level)

Valley below the sea level = 12 and half ft = (-12.5) ft

Distance between the summit and the valley = 8050 - (-12.5)

                                                                           = 8050 + 12.5

                                                                           = 8062.5 ft

Therefore, Vertical distance = 8062.5 ft will be the answer.
