Gillian and Nicole took part in a cycling race. Gillian cycled at a speed of 15 km/h. Both of them did not change their speed throughout the race. When Nicole covered ¹₅ the distance, Gillian was 5.8 km in front of her. Gillian reached the finishing line at 8.41 a.m. What time did Nicole reach the finishing line?
If Gillian continued to cycle until Nicole reaches the finishing point, the extra distance she covered
= 5 x 5.8
= 29 km

Time taken by Nicole to complete the race
= Time taken by Gillian to cycle 29 km
= ²⁹₁₅ 
= 1¹⁴₁₅ h

1 h = 60 min
1¹⁴₁₅ h = 1¹⁴₁₅ x 60 = 116 min

116 min after 8.41 a.m.: 10.37 a.m.

Time that Nicole reached the finishing line: 10.37 a.m.

Answer(s): 10.37 a.m.
