Parshotam and Anjika started moving in opposite directions from the same place at speeds of 30 km/h and 3.5 km/h respectively. How far apart will they be after 2.5 hours?

Correct option is D

Given:
Speed of Parshotam = 30 km/h
Speed of Anjika = 3.5 km/h
Time = 2.5 hours
Formula Used:
Distance = Speed × Time
Solution:
Distance covered by Parshotam in 2.5 hours = 30 × 2.5 = 75 km
Distance covered by Anjika in 2.5 hours = 3.5 × 2.5 = 8.75 km
Since they are moving in opposite directions,
Total distance between them after 2.5 hours = 75 + 8.75 = 83.75 km

Alternate Solution:
Relative Speed = 30 + 3.5 = 33.5 km/h
Distance after 2.5 hours = 33.5 × 2.5 = 83.75 km
