If a car travels 40 mph for a distance of 1680 miles, how much time did it take?

42 hour

Explanation:

It is given that,

Speed of a car, v = 40 mph

Distance covered by the car, d = 1680 miles

We need to find the time taken by the car to cover this distance. We can find it using the formula of speed which is equal to the distance covered divided by the time taken. Let the time is t.

speed = distance/time taken

Hence, the car will take 42 hours to cover 1680 miles with a speed of 40 mph.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
