Victoria and Barbara took part in a cycling race. Victoria cycled at a speed of 39 km/h. Both of them did not change their speed throughout the race. When Barbara covered ¹₂ the distance, Victoria was 6.5 km in front of her. Victoria reached the finishing line at 11.46 a.m. What time did Barbara reach the finishing line?
If Victoria continued to cycle until Barbara reaches the finishing point, the extra distance she covered
= 2 x 6.5
= 13 km

Time taken by Barbara to complete the race
= Time taken by Victoria to cycle 13 km
= ¹³₃₉ 
= ¹₃ h

1 h = 60 min
¹₃ h = ¹₃ x 60 = 20 min

20 min after 11.46 a.m.: 12.06 p.m.

Time that Barbara reached the finishing line: 12.06 p.m.

Answer(s): 12.06 p.m.
