If a bus traveled 20 miles north on a straight path, and then traveled 20 miles back to the starting point, what would the velocity of the bus be?

The velocity of the bus be is 0 miles/second

Explanation:

Given, a bus travelled a distance of 20 miles north and 20 miles back to the starting point

Hence, total distance = 20 + 20 = 40 miles

Velocity is calculated by the formula:

Velocity =  

Displacement =

Velocity =

Therefore, the velocity of the bus is 0 miles/second

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
