Problema Solution
a car travelled the first 240 kilometer at a certain speed and then, the next 192 kilometers 8kph faster than its initial speed. what is its initial speed if the entire trip took 10 hours
Answer provided by our tutors
Let 'v' represent the initial speed then 'v + 8' is the increased speed.
Since speed = distance/time we have:
240/v + 192/(v + 8) = 10

........
v = 40 kph
The initial speed was 40 kph.
