Maxwell leaves his home and walks toward Brad's house at the same time that Brad leaves his home and runs toward Maxwell's house. If the distance between their homes is 30 kilometers, Maxwell's walking speed is 4 km/h, and Brad's running speed is 6 km/h, what is the distance traveled by Brad?
Answer/Solution
18
Steps/Work
Time taken = Total Distance / Relative Speed
Total Distance = 30 kms
Relative Speed (Opposite side) (As they are moving towards each other speed would be added ) = 6+ 4 = 10 kms/hr
Time taken = 30 / 10 = 3 hrs
Distance traveled by Brad = Brad's speed * time taken = 6 * 3 = 18 kms... Answer - B
