a small airplane flies a straight line at the speed of 225 km/hrs. How long does it takes the plane to fly in 30 km in minute, hours and seconds?
30 km (1 hour/225 km) = .1333333...
= (.1 + 1/30) hours
.1 hours = .1*60 minutes
= 6 minutes
(1/30) hours (60 min/hour)
=2 minutes
6 + 2 = 8 minutes
To determine the time it takes for the small airplane to fly a distance of 30 km, we need to use the formula:
Time = Distance / Speed
Given that the speed of the airplane is 225 km/hr and the distance it needs to cover is 30 km, we can calculate the time it takes:
Time = 30 km / 225 km/hr
To express the answer in minutes, we need to convert the time from hours to minutes. There are 60 minutes in an hour, so:
Minutes = (30 km / 225 km/hr) * 60 min/hr
To express the answer in seconds, we need to convert the time from hours to seconds. There are 3600 seconds in an hour, so:
Seconds = (30 km / 225 km/hr) * 3600 sec/hr
Now, let's calculate the time it takes for the airplane to fly 30 km in minutes and seconds:
Minutes: (30 km / 225 km/hr) * 60 min/hr
Seconds: (30 km / 225 km/hr) * 3600 sec/hr
