Answer:
Δd = 25.9115 km
Step-by-step 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
