Answer 1

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.
