Basic Speed | Time, Speed & Distance Aptitude Practice | Kuriloo

Governed by the relationship: Distance = Speed × Time. From this, Speed = Distance / Time, and Time = Distance / Speed.

To convert kilometers per hour (km/h) to meters per second (m/s), multiply the speed by 5/18. To convert m/s to km/h, multiply by 18/5.

Always verify that distance and time units match your speed unit (e.g., matching kilometers with hours, or meters with seconds) before executing calculations.
When distance is held constant, speed and time share an inversely proportional relationship ($S_1 / S_2 = T_2 / T_1$).

If a person travels at a ratio of speeds a:b over the exact same distance, the ratio of time taken to cover that distance will always be b:a.

baseline transformation example frequently used to test dimensional analysis precision.

Problem QueryA vehicle drives at a constant speed of 72 km/h. Calculate the total distance in meters covered by the vehicle in 25 seconds.

Step-By-Step Solution Path

Step 1: Convert the speed from km/h to m/s: 72 × (5/18) = 4 × 5 = 20 m/s.

Step 2: Use the baseline motion formula to find distance: Distance = Speed × Time.

Step 3: Multiply the parameters: 20 m/s × 25 seconds = 500 meters.

Analytical Hint: Convert your speed tracking unit into meters per second first to match the given time frame.
