6. Every morning I use 1 cup of Bisquick pancake mix to make pancakes for my kids. How many boxes of Bisquick do I use in 1 year? 7. How many meters per second (m/s) is a car moving if it is going 55 MPH? Hints: "MPH" is miles per hour or (miles/hour). A car that moves at 55 MPH is going 55 miles for every 1 hour, and the car travels 110 miles after 2 hours, 220 miles after 4 hours, etc. 110 miles 110 miles per hour = 55 miles per hour. 2 %3D Notice that the miles divided by time is 2 hours So, if a car is going 55 miles per hour, convert 55 miles into meters, convert 1 hour into seconds, and meters or then divide the answers to calculate meters per second (or nd second -).
