Respuesta :

Answer:

Yes

Explanation:

The speed of the driver = 50 km/h

Time spent = 45 minutes = 0.75 h

From the definition of speed;

 Speed = distance/time

Hence,

  Distance = speed x time

  Distance covered by driver in 45 minutes = 50 x 0.75 = 37.5 km

  Distance needed to be covered = 30 km.

Therefore, the driver has traveled far enough to reach the office.

The driver has travelled far enough to reach the office i.e. True

Given data :

The speed of the driver = 50 km/h

Distance from office = 30 km

Time travelled by driver = 0.75 h

Determine the distance travelled so far by the driver

Speed = Distance / time

∴ Distance = Speed * time

                  = 50 * 0.75  = 37.5 km

Given that the distance travelled by the driver ( 37.5 km ) is greater than the distance from the office ( 30 km ) the driver has travelled far enough to reach the office.
