Pamela left home at 11.30 a.m. and drove towards the suburb. 3 hours later, her uncle left their home and drove towards the same suburb at 95 km/h. When the uncle reached the suburb at 7.30 p.m., Pamela had another 3 km to travel. What was Pamela’s average speed? Express your answer in mixed number.
Time that the Pamela's uncle started driving = 2.30 p.m.
Duration that Pamela's uncle drove from 2.30 p.m. to 7.30 p.m. = 5 h

Distance that Pamela's uncle travelled
= 5 x 95
= 475 km

Distance that Pamela travelled by the time her uncle reached the city
= 475 - 3
= 472 km

Time that Pamela took to travel 472 km = 8 h

Pamela's average speed
= 472 ÷ 8
= 59 km/h

Answer(s): 59 km/h
