Ravi and Mohan start moving together from a point in opposite directions on bikes. Ravi’s speed is 80 km/h and Mohan’s speed is 40 km/h. What will be the distance between them after 15 min?

Correct option is B

Given:

Ravi’s speed is 80 km/h and Mohan’s speed is 40 km/h.

Formula Used:
Distance = Speed $$\times$$​ Time
Solution:

The time is given as 15 minutes, which is equivalent to:
$$\frac{15}{60}$$​ = 0.25 hours.
The distance covered by Ravi in 15 minutes is:
80$$\times$$​ 0.25 = 20 km
The distance covered by Mohan in 15 minutes is:
40 $$\times$$​ 0.25 = 10 km
The total distance between them is:
20 + 10 = 30 km
Thus, the distance between Ravi and Mohan after 15 minutes is 30 km.
