Question

Question 7 (1 point)Mr. Jolly drove 90 km per hour on South Luzon Blvd. this morning. How many metersper second is this rounded to the nearest tenth? (1000m = 1km)

Answer 1

We need to convert 90 km/h (kilometers per hour) to m/s (meter per second)

For this we need the following information:

1 kilometer = 1000 meters ----> 1km =1000m

1 hour = 3600 seconds ----> 1h = 3600s

And now we multiply:

This will cancel the hour units and change them by seconds, and cancel the km units and change them by meters. So we get that we need to divide 90km by 3600 and then multiply by 1000:
