An airplane travels at 950 km/h. how long does it take to travel 1.00 km

First calculate the percentage of one hr it takes. You can do this by dividing the distance by the velocity. The general formula for this is:



always remember to make sure your units are the same.

so that's 1km by the 950km/h velocity.

1/950 = 0.0010526 hrs

Then multiply that answer by 3600 (the number of seconds in 1 hr) to find how many seconds this is.

0.0010526 * 3600 = 3.789 seconds

The magnets are probably damaged or there not strong enough to attached to the refrigerator

The answer is trial 3.
