A car travels from Los Angeles to San Diego, a distance of 120 miles in 1 hour and 45 minutes. What was the car's average speed?

68.57 miles per hour

Explanation:

Given data

Distance= 120 miles

Time= 1 hours 45 minutes

Let us convert the time all to hours

45 minutes to hours is 0.75 hours

Hence the time in hours is

=1+0.75

=1.75 hours

Also, the expression for the speed is given as

Speed= distance/time

Substitute

Speed= 120/1.75

Speed= 68.57

Hence the speed is 68.57 miles per hour

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.
