**A car is traveling at a rate of 20 meters per second. What is the car’s rate in kilometers per hour? How many kilometers will the car travel in 3 hours? Do not round your answers.**

**Answer:**

1 hour = 60 x 60 secs= 3600

1 km= 1000 meters

To convert m/s into km/s, multiply by 3.6 (60 x 60 ÷1000)

Hence 20m/s = (20 x 3.6) km/hr

=72km/hr.

Distance = Speed x Time

Hence Distance= 72km/hr x 3 hr

= 216 km travelled.
