Kimberly and Natalie took part in a cycling race. Kimberly cycled at a speed of 20 km/h. Both of them did not change their speed throughout the race. When Natalie covered ¹₅ the distance, Kimberly was 5.6 km in front of her. Kimberly reached the finishing line at 10.35 a.m. What time did Natalie reach the finishing line?
If Kimberly continued to cycle until Natalie reaches the finishing point, the extra distance she covered
= 5 x 5.6
= 28 km

Time taken by Natalie to complete the race
= Time taken by Kimberly to cycle 28 km
= ²⁸₂₀ 
= 1²₅ h

1 h = 60 min
1²₅ h = 1²₅ x 60 = 84 min

84 min after 10.35 a.m.: 11.59 a.m.

Time that Natalie reached the finishing line: 11.59 a.m.

Answer(s): 11.59 a.m.
