Linda left home at 11.40 a.m. and drove towards the province. 2 hours later, her mother left their home and drove towards the same province at 95 km/h. When the mother reached the province at 4.40 p.m., Linda had another 2 km to travel. What was Linda’s average speed? Express your answer in mixed number.
Time that the Linda's mother started driving = 1.40 p.m.
Duration that Linda's mother drove from 1.40 p.m. to 4.40 p.m. = 3 h

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

Distance that Linda travelled by the time her mother reached the city
= 285 - 2
= 283 km

Time that Linda took to travel 283 km = 5 h

Linda's average speed
= 283 ÷ 5
= 56³₅ km/h

Answer(s): 56³₅ km/h
