A car travels at a constant speed of 72kmh calculate the distance the car will travel in 30 seconds?
First we need to convert 30 seconds in hour or convert the constant speed in m/s. I convert 30 second in hour; 30s=0.083h V=d/t. d=v.t d=72km/h.(0.0083) d=0.6km II convert 72km/h in m/s calculate the distance v=72km/h .(1000m/3600s), so 72km/h=20m/s we can calculate the distance v=d/t, so d=v.t d=20m/s.(30) d=600m or 0.6km
