Answer:

Distance between 2 stations= 8.94 miles

Step-by-step explanation:

The coordinates of Symphony Station is given by:

Symphony Station: (x₁ , y₁) : (1,2)

The coordinates of Elm station is given by:

Elm Station: (x₂ ,y₂) : (-3,-6)

We know that the distance formula can be used to find distance between these 2 points. Distance formula is given as

d= √((x₂ - x₁)² + (y₂ - y₁) ²)

Substitute values

d= √((-3 - 1)² + (-6 - 2) ²)

d= √((-4)²+(-8)²)

d= √(16+64)

d=√80

d= 8.94 miles

Cruz is training to compete in a triathlon. He left his house at 6 : 00 and ran until 7 : 30 . Then he rode his bike until 9 : 4

uysha [10]

Answer:

The correct answer is Cruz's running speed is 10 miles per hour and his biking speed is 16 miles per hour.

Step-by-step explanation:

Let the speed of Cruz when running is s miles per hour and speed of cruz biking is 1.6s miles per hour.

Cruz ran for 90 minutes and rode is bike for 135 minutes.

Total distance covered by Cruz is $\frac{90}{60}$ × s + 1.6s × $\frac{135}{60}$

This distance is given to be 51 miles.

⇒ $\frac{90}{60}$ × s + 1.6s × $\frac{135}{60}$ = 51

⇒ 90s + 216s = 3060

⇒ 306s = 3060

⇒ s = 10

Cruz's running speed is 10 miles per hour and his biking speed is 16 miles per hour.
