Gabby left home at 10.35 a.m. and drove towards the province. 3 hours later, her auntie left their home and drove towards the same province at 95 km/h. When the auntie reached the province at 6.35 p.m., Gabby had another 5 km to travel. What was Gabby’s average speed? Express your answer in mixed number.
Time that the Gabby's auntie started driving = 1.35 p.m.
Duration that Gabby's auntie drove from 1.35 p.m. to 6.35 p.m. = 5 h

Distance that Gabby's auntie travelled
= 5 x 95
= 475 km

Distance that Gabby travelled by the time her auntie reached the city
= 475 - 5
= 470 km

Time that Gabby took to travel 470 km = 8 h

Gabby's average speed
= 470 ÷ 8
= 58³₄ km/h

Answer(s): 58³₄ km/h
