A person walks at a speed of 6 km/h and covers a certain distance in 4 hours. If the person increases the speed to 8 km/h, how long will it take to cover the same distance?

Correct option is C

Given: Speed1 = 6 km/h, Time1 = 4 hours, Speed2 = 8 km/h
Formula Used: Distance = Speed * Time, New time = Distance/Speed2
Solution:
Distance covered = 6 * 4 = 24 km
New time = 24/8 = 3 hours
