Question

Trisha ran 10 kilometers in 2.5 hours. Jason ran 7.5 kilometers in 2 hours. Olga ran 9.5 kilometers in 2.25 hours. Who had the fastest average speed?

Answer 1

Olga had the fastest average speed at
`4.22 km/h` when comparing her speed with Trisha
`(4 km/h)` and Jason
`(3.75 km/h)`.

Step-by-step explanation:

To determine who had the fastest average speed between Trisha, Jason and Olga, we need to calculate the speed for each person. Speed is calculated by dividing distance traveled by the time taken.

• 
  `Trisha's speed = distance / time = 10 km / 2.5 h = 4 km/h`
• 
  `Jason's speed = 7.5 km / 2 h = 3.75 km/h`
• 
  `Olga's speed = 9.5 km / 2.25 h = 4.22 km/h`

Comparing these speeds, we find that Olga had the fastest average speed at
`4.22 km/h.`
