A driver needs to make a delivery to an office that is 30 km away. The driver has traveled for 45 minutes west down a straight road at 50 km/h. a. Has the driver traveled far enough to reach the office?

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.
