Nidhi and Ria are very close friends. Nidhi’s parents own a Maruti Alto. Ria’s parents own a Toyota Liva. Both the families decide to go for a picnic to Somnath temple in Gujrat by their own cars. Nidhi’s car travels x km/h while Ria’s car travels 5 km/h more than Nidhi’s car. Nidhi’s car took 4 hrs more than Ria’s car in covering 400 km. What will be the distance covered by Ria’s car in two hour?

Answer»

`2(x + 5) km`
`(x - 5) km`
`2(x + 10) km`
`(2x + 5) km`

SOLUTION :NIDHI’s car travels x km/h while Ria’s car travels 5 km/h more than Nidhi’s car. Thus Ria’s car SPEED is x + 5 km/hour. Distance covered in two hour is 2(x + 5) .
Thus (a) is correct option.
