Pamela left home at 11.45 a.m. and drove towards the town. 2 hours later, her father left their home and drove towards the same town at 92 km/h. When the father reached the town at 5.45 p.m., Pamela had another 5 km to travel. What was Pamela’s average speed? Express your answer in mixed number.
Time that the Pamela's father started driving = 1.45 p.m.
Duration that Pamela's father drove from 1.45 p.m. to 5.45 p.m. = 4 h

Distance that Pamela's father travelled
= 4 x 92
= 368 km

Distance that Pamela travelled by the time her father reached the city
= 368 - 5
= 363 km

Time that Pamela took to travel 363 km = 6 h

Pamela's average speed
= 363 ÷ 6
= 60¹₂ km/h

Answer(s): 60¹₂ km/h
