Raeann left home at 11.25 a.m. and drove towards the campsite. 2 hours later, her mother left their home and drove towards the same campsite at 95 km/h. When the mother reached the campsite at 4.25 p.m., Raeann had another 3 km to travel. What was Raeann’s average speed? Express your answer in mixed number.
Time that the Raeann's mother started driving = 1.25 p.m.
Duration that Raeann's mother drove from 1.25 p.m. to 4.25 p.m. = 3 h

Distance that Raeann's mother travelled
= 3 x 95
= 285 km

Distance that Raeann travelled by the time her mother reached the city
= 285 - 3
= 282 km

Time that Raeann took to travel 282 km = 5 h

Raeann's average speed
= 282 ÷ 5
= 56²₅ km/h

Answer(s): 56²₅ km/h
