Problema Solution
A bike race consists of two segments whose total length is 110 km. The first segment is covered at 15 kph and takes 2 hours longer to complete than the second segment, which is covered at 25 kph. How long is each segment?
Answer provided by our tutors
let the first segment is of length x then the second segment is y
thus,
we have
x+y=110 total length
and
x/15=y/25+2
=> x/15-y/25=2
solve this two equation we get
x=60km and y=50km
thus two segemnt are 50km and 60 km
