Kylie left home at 11.10 a.m. and drove towards the countryside. 2 hours later, her auntie left their home and drove towards the same countryside at 95 km/h. When the auntie reached the countryside at 4.10 p.m., Kylie had another 2 km to travel. What was Kylie’s average speed? Express your answer in mixed number.
Time that the Kylie's auntie started driving = 1.10 p.m.
Duration that Kylie's auntie drove from 1.10 p.m. to 4.10 p.m. = 3 h

Distance that Kylie's auntie travelled
= 3 x 95
= 285 km

Distance that Kylie travelled by the time her auntie reached the city
= 285 - 2
= 283 km

Time that Kylie took to travel 283 km = 5 h

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

Answer(s): 56³₅ km/h
