Kimberly and Vanessa took part in a cycling race. Kimberly cycled at a speed of 40 km/h. Both of them did not change their speed throughout the race. When Vanessa covered ¹₅ the distance, Kimberly was 6.4 km in front of her. Kimberly reached the finishing line at 9.43 a.m. What time did Vanessa reach the finishing line?
If Kimberly continued to cycle until Vanessa reaches the finishing point, the extra distance she covered
= 5 x 6.4
= 32 km

Time taken by Vanessa to complete the race
= Time taken by Kimberly to cycle 32 km
= ³²₄₀ 
= ⁴₅ h

1 h = 60 min
⁴₅ h = ⁴₅ x 60 = 48 min

48 min after 9.43 a.m.: 10.31 a.m.

Time that Vanessa reached the finishing line: 10.31 a.m.

Answer(s): 10.31 a.m.
