3.  Mr. kavin walks at 4/5 of his normal speed and takes 60 minutes more than the usual time. What will be the new time taken by Mr.kavin?

260 minutes
235 minutes
220 minutes
300 minutes

```Answer

Answer: Option  D Explanation:4/5 of speed = 5/4 of original time
5/4 of original time = original time + 60 minutes
1/4 of original time = 60 minutes
Thus, original time = 60*4 = 240 minutes = 240+60 = 300 minutes ```

4.  A truck travelled to a place Q from P, The first 50 km at 10 kmph faster than the usual speed, but it returned the same distance at 10 kmph slower than usual speed. If the total time taken by the truck is 12 hours, then how many hours will travel at the faster speed?

8 hours
6 hours
2 hours
3 hours

```Answer

Answer: Option  C Explanation:Total time taken,
{50/(x - 10)} + 50/(x+10)} = 12 hours
By solving the equation, we get
x = 15
time is taken by the truck at faster speed = 50/(15+10) = 2 hours. ```
