Detailed Solution

Given that a car is travelling 60 km in 2 h.
We need to find the distance travelled by the car in 6 h, if the speed remains constant.
Assume that distance covered in 6 hrs is

d

km.
Understand that distance and time are in direct proportion for a given speed and hence the ratio of distance and time will be constant.

constant = \frac{distance}{time}

Equate the ratio of 60 km and 2 h with ratio of

d

km and 6 h and solve for

d

\frac{d}{6} = \frac{60}{2}

\frac{d}{6} = 30

d = 30 \times 6

d = 180

Therefore, the distance travelled in 6 h is 180 km.
Hence, the correct option is 3.
