Question: A ship went on a voyage. After it had traveled 180 miles a plane started with 10 times the speed of the ship. Find the distance when they meet from starting point.
Answer:
Given that speed of the plane is 10 times the speed of the ship. So it is obvious that the distance covered by plane will be 10 times the distance covered by the ship for the given time.
i.e. Distance covered by plane = 10 * (Distance covered by ship after plane started)
Now from the given data,
Distance covered by plane = 180 + Distance covered by ship after plane started
10 * (Distance covered by ship after plane started) = 180 + Distance covered by ship after plane started
9 * (Distance covered by ship after plane started) = 180
Distance covered by ship after plane started = 20 miles
Total distance covered by ship from starting point
= 180 + 20
= 200 miles
