Jen left home at 11.35 a.m. and drove towards the seaside resort. 3 hours later, her cousin left their home and drove towards the same seaside resort at 94 km/h. When the cousin reached the seaside resort at 7.35 p.m., Jen had another 2 km to travel. What was Jen’s average speed? Express your answer in mixed number.
Time that the Jen's cousin started driving = 2.35 p.m.
Duration that Jen's cousin drove from 2.35 p.m. to 7.35 p.m. = 5 h

Distance that Jen's cousin travelled
= 5 x 94
= 470 km

Distance that Jen travelled by the time her cousin reached the city
= 470 - 2
= 468 km

Time that Jen took to travel 468 km = 8 h

Jen's average speed
= 468 ÷ 8
= 58¹₂ km/h

Answer(s): 58¹₂ km/h
