Nicole left home at 10.55 a.m. and drove towards the town. 3 hours later, her uncle left their home and drove towards the same town at 94 km/h. When the uncle reached the town at 6.55 p.m., Nicole had another 4 km to travel. What was Nicole’s average speed? Express your answer in mixed number.
Time that the Nicole's uncle started driving = 1.55 p.m.
Duration that Nicole's uncle drove from 1.55 p.m. to 6.55 p.m. = 5 h

Distance that Nicole's uncle travelled
= 5 x 94
= 470 km

Distance that Nicole travelled by the time her uncle reached the city
= 470 - 4
= 466 km

Time that Nicole took to travel 466 km = 8 h

Nicole's average speed
= 466 ÷ 8
= 58¹₄ km/h

Answer(s): 58¹₄ km/h
