The cruising speed of an airplane is approximately 900 kilometers per hour. What is this speed in meters per second? Enter your answer as an number without units.

250

Step-by-step explanation:

900 kilometers = 900000 meters

( multiply kilometers by 1000 to get meters )

1 hour = 3600 seconds

900,000/3,600 = 250

so the speed of the plane is 250 meters per second.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
