Question

A cruise ship makes the 1,500-mile trip from London to Athens in 83 1 3 hours. If it travels 10 miles per hour FASTER on the return trip, the return trip will take

Answer 1

Answer: He will take 53.57 hours in returning the trip

Explanation:

Since we have given that

Distance traveled by a cruise ship = 1500 miles

Time taken to travel from London to Athens is given by

$83\frac{1}{3}\ hours$

Now,

Speed is given by

$\frac{Distance}{Time}={\frac{1500}{\frac{250}{3}}=18\ hours$

Now,

if he increase the speed 10 miles per hour

So, new speed becomes

$18+10=28\ hours$

Time taken in returning trip will be

$\frac{Distance}{Speed}=\frac{1500}{28}=53.57\ hours$

Hence, he will take 53.57 hours in returning the trip.
