Klara and Jitka went on a hiking trip at 13 o'clock at speed 5km/h. At 14 o'clock, Tomas ride on the bike at an average speed of 28 km/h. How many hours and at what distance from the beginning of the road Tomáš caught the two girls?

Result

t = hh:mm (Correct answer is: 14/13) Wrong answer
s =  6.087 km

Solution:

s1=s2 v1 (t13)=v2 (t14)  5 (x13)=28 (x14)  23x=327  x=3272314.217391  t=14:13
s=5 (x13)=5 (14.217413)=14023=6.087 km



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
