. An aeroplane takes off at sea level and ascends in a straight line until reaching an altitude of 3000 metres. The distance travelled during the ascent is 13.5 kilometres. What is the
gradient of the ascent?

Will give brainliest and extra points for the correct answer!!

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

its 50 miles away from the starting point

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
