Explanation:
A helicopter travels 17.5m south in 40 seconds. Determine your speed in m / s and km / h
Given that,
A helicopter travels a distance of
d = 17.5m
And it takes a 40seconds to travel the distance
then, time taken = 40seconds
t = 40 seconds
Speed is the rate at which distance is travelled.
Speed can be calculated at the distance covered over the time taken.
Speed = distance / Time taken
S= d / t
S= 17.5 / 40
S= 0.4375 m/s
To km/hr
We know that,
1 km = 1000m
1 hr = 60minutes
1minutes = 60seconds
Then, 1 hr = 60mins × 60secs/mins
1hr = 3600seconds
Then,
S= 0.4375m/s × (1km / 1000m) × (3600s / 1hr)
Then, s= 1.575 km/hr
Check attachment for better understanding of the mathematical expression
So, the speed is
In m/s: S= 0.4375 m/s
In km/hr: s= 1.575 km/hr
Dado que,
Un helicóptero recorre una distancia de
d = 17.5m
Y lleva unos 40 segundos recorrer la distancia
entonces, tiempo tomado = 40 segundos
t = 40 segundos
La velocidad es la velocidad a la que se recorre la distancia.
La velocidad se puede calcular a la distancia recorrida en el tiempo necesario.
Velocidad = distancia / tiempo necesario
S = d / t
S = 17.5 / 40
S = 0,4375 m / s
In spanish
A km / h
Lo sabemos,
1 km = 1000m
1 hora = 60 minutos
1 minuto = 60 segundos
Entonces, 1 hora = 60 minutos × 60 segundos / minuto
1 hora = 3600 segundos
Entonces,
S = 0,4375 m / s × (1 km / 1000 m) × (3600 s / 1 hora)
Entonces, s = 1.575 km / h
Verifique el archivo adjunto para una mejor comprensión de la expresión matemática
Entonces, la velocidad es
En m / s: S = 0.4375 m / s
En km / h: s = 1.575 km /
