A cheetah can run at 30 m/s but only for a but 12 s. how far will it run in that time

ANSWER: 360metres

EXPLANATION:

Distance= speed × time

=30×12

= 360metres

Explanation:speed=30m/s time=12 sec                                                                                             now,distance=speed x time taken                                                                                                                                   or,distance=30 x 12                                                                                                                                                                                                                                                                         Therefore,distance=360m

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
