Correct Answer - Option 4 : 27 km
Given,
Vinod and Geeta walk in opposite directions at the rate of 4 km and 5 km per hour respectively
Formula used
distance = speed × time
Calculations:
sum of their individual speed = 4 + 5 = 9 km/hour
Distance covered in 3 hours = time × speed
⇒ 3 × 9 = 27 km
.∴ The required answer is 27 km
