Question

P and q travel the same distance through the car in the opposite direction at speed of 27 km/hr and 81 km/hr. The total time taken by them is 80 seconds together. Find the distance traveled by both of them.

Answer 1

Answer:

distance travelled by p+q= 2.4 km

Answer 2

Answer:

900 m

Explanation:

Let the total distance travelled by P and Q be m km.

It is given that both travelled the same distance.

Ratio of speed = 1 : 3

So, the ratio of time taken will be inverse i.e. 3 : 1

So, the time taken by P = (3/4) × 80 = 60 secs

Time taken by Q = 20 secs

Distance travelled by P = 27 × (5/18) × 60 = 450 m

Distance covered by Q = 81 × (5/18) × 20 = 450 m

Total distance travelled = 900 m
