Given : Un coche viaja a 90 km/h, y recorre cierta distancia en 3,5 h.
To find : Calcula el tiempo que tardaria en recorrer esa misma distancia si viajara a 120 km/h.
Solution:
A car travels at 90 km / h, and travels a certain distance in 3.5 h.
Calculate the time it would take to run that same distance if you were traveling at 120 km / h.
car travels at 90 km / h
Speed = 90 km/h
Time = 3.5 h
Distance = Speed * Time
=> Distance = 90 * 3.5 = 315 km
Now Speed = 120 km/h
Time = 315 / 120 = 2.625 hr = 2 hr 37 minutes 30 sec
viajes en automóvil a 90 km / h
Velocidad = 90 km / h.
Tiempo = 3.5 h
Distancia = Velocidad * Tiempo
=> Distancia = 90 * 3.5 = 315 km
Ahora velocidad = 120 km / h
Tiempo = 315/120 = 2.625 h = 2 h 37 minutos 30 seg.
