Answer 2

car B is moving at the fastest speed.

Given:

Speed of car A = 85 km/ hour

Speed of car B =25 m/s

Find:

Fastest moving car

Solution:

• SI unit of speed is in m/s.
• So let us convert 85 km/s to m/s.
• 1 km = 1000m
• 1 hour = 60 * 60 = 3600 seconds
• 1 km/hour = 1000m/3600s = 5/18 m/s
• 85 km/hour = 85* (5/18) = 23.611 m/s
• So car A moves with a speed of 23.611 m/s.
• Car B moves with a speed of 25 m/s.
• So car B is moving fastest.
