Assuming that average speed are in kilo-metres per hour, the typical trip takes 2 hours and 20 minutes to complete.

Apply the following formula to this issue:

Total distance travelled minus total time taken equals average speed.

You must first determine the length of the trip travelled.

Total distance travelled minus total time taken equals average speed.

Therefore : d = average speed x time spent overall - rearranging

In other words, d = vt = 105 km/hr x 2.3333... hrs = 245 km

Find out how long the typical journey takes on Friday afternoon.

t = d/v - equation rearranged equals 245 km/67 km/h = 3.6567164.

18 hours equals 3 hours, 39 minutes (rounded to nearest whole minute)

You must now determine how much longer the Friday trip takes.

Duration: (3 hours and 39 minutes) - (2 hours and 20 minutes)

= 1 hour and 19 minutes
