Question 15 David went for a run in his town. He ran from his house to the school, which is 1.22 miles. Then he ran 3 laps around the school track. Each lap is 0.25 miles. Then he ran halfway to the gas station. The distance from the school track to the gas station is 2.68 miles. Finally he ran straight home, which is 0.49 miles. What is the total distance David ran?

Respuesta :

Distance covered to travel house and school, d1 = 1.22 miles.

Distance covered in 3 laps, d2 = 3 × 0.25 = 0.75 miles.

Distance between halfway to the gas station from school,

d3 = 2.68÷2 = 1.34 miles.

Distance from his last position to home, d4 = 0.49 miles.

So, total distance covered is :

[tex]D = d1+d2+d3+d4\\\\D=(1.22+0.75+1.34+0.49)\ miles\\\\D=3.8\ miles[/tex]

Therefore, total distance covered is David is 3.8 miles.

Hence, this is the required solution.
