- We travel from Winnipeg to Regina and back. The total distance is 1100km. The return to Winnipeg is made in a snowstorm at an average speed of 20km/h slower than the outward journey. If the whole trip took 13 hours, what is the average speed in each direction?arrow_forwardAs you are driving to school one day, you pass a construction site of a new building and you stop to watch for a few minutes. A crane is lifting a batch of bricks on a pallet to an upper floor of the building. Suddenly a brick falls off the rising pallet. You measure the time it takes for the brick to hit the ground and you find it to be 2.5 seconds. The crane has height markings. You saw the brick fell off the pallet at a height of 30.7 meters above the ground. A falling brick can be dangerous, and you wonder how fast the brick was moving when it hit the ground. Since you are taking physics, you quickly calculate the answer.arrow_forwardA girl runs 2.5 km East to the end of a road, turns around and continues to keep running West for 1 km.
