How many seconds are in one day?
86,400 s 1 day 24 hr 60 mins 60 sec 1 day 1 hour 1 min 1 x 24 x 60 x 60 = 86,400 s
A woman jogs for 2.0 hours covering a distance of 13 kilometers. What is the speed of the woman expressed in kilometers per hour?
d = 13 km t = 2.0 hr s = ? s = d / t s = 13 km/2.0 hr s = 6.5 km/hr
If an automobile travels at 30 m/s for 2 mins., how many meters does it travel?
d = ? t = 2 mins = 120 s s = 30 m/s d = s x t d = 30 m/s x 120 s d = 3600 m
In one-half hour, a bicyclist traveled 20 km. What was the bicyclist’s speed?
d = 20 km t = 0.5 hr s = ? s = d / t s = 20 km / 0.5 hr s = 40 km/hr
If you traveled 225 km at 75 km/hr, how long did you travel?
d = 225 km t = ? s = 75 km/hr t = d / s t = 225 km / 75 km/hr t = 3 hr
