Felicia left Rome at 8 AM & drove her Ferrari at 80mp0h from Rome to Sorrento. She then took the boat to Capri for the day, returning to Sorento 5hrs later. On the return trip from Sorrento to Rome she averaged 60mph & arrived in Rome ar 8PM. Howfar is it from Rome to Sorrento?
From 8 Am to 8 Pm is 12 hrs. The round trip to Capri took 5 hrs that means:
She was a total of 7 hrs on the road.
Let d = distance from Rome to Sor,
Write a time equation; Time = Distance/speed
Mult equation by 240 to get rid of the denominators:
3d + 4d = 7(240)
7d = 7/240)
Divide equation by 7:
d = 240 mi from Rome to Sorrento
Check: 240/80 + 240/60 = 7 hrs
