What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass

Achild has maximum walking speed of 1.6 m/s. what is the length of the child's legs? 0.26 m
