(002) By using the equation, velocity = distance / time, we can find the time as follows:

40 km/h = 149km / time

Then by rearranging the equation,

Time = 149 km / 40 km/h

= 3. 725 hours = 3.7 hours (rounded up)

(003) Now we should again calculate the time using the new velocity as follows:

Time = 149 km / 59.9 km/h

= 2.5 hours

To calculate how much time is saved, we have to substract the initial time with the new time;

Therefore, Time saved = 3.7 h - 2.5 h

= 1.2 hours = 72 minutes.
