(a) 240 km
(b) 300 km
(c) 320 km
(d) 360 km

Answer: (c) 320 km 

Explanation:

Let total Journey = x km.

Ist hour, he travelled  = x/4 km.

Next hour, he travelled = x/2 km

Total distance travelled  = (x/4) + (x/2) = 3x/4 km

Remaining distance = (x - 3x/4) km = x/4 km

It is given that, last

last 30 min, he travelled = 80 km

x/4 = 80 km

x = 320 km.

9 + 5 = 445 = (9 – 5) (9 × 5)

6 + 2 = (6 – 2) (6 × 2) = 412
