Calcula la distancia (en km) que Larry recorre si mantiene una rapidez promedio 8,7 km/h durante 173,7 minutos

   Δd = 25.9115 km

Explanation:

Average speed is defined by the distance traveled between the time spent

          v = Δd / Δt

in this case they give us the speed of 8.7 km / h and the time of 173.7 min

let's reduce to the SI system

          v = 8.7 km / h (1000 m/ 1 km) (1h / 3600s) = 2,416 m / s

          t = 173.7 min (60s / 1min) = 10722 s

the distance is

          Δd = v Δt

          Δd = 2.4166 10722

          Δd = 25,911.5 m

we reduce to km

         Δd = 25.9115 km

it is the second option.

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.
