4.  or x sp t d ÷ 1.Write down what you need to find with = 2.Remove it from the shape – cover it up 3.Write the remaining formula 4.Watch for cancelling units sp = dtdt d =d = t=t= d sp sp  t

5. GivenFormulaSetupSolution List Given Info And Unknown: d = 50 miles t = 2 hours sp = ? Show Needed Equations: sp = ------------ Substitute with Units & Show Math: sp = -------------- Circles Answer with Units: sp = 25 mi/hr 50 miles 2 hours t d Problem: If you travel 50 miles in 2 hours, what was your speed?

6. 1. Calculate the speed of a motorcycle traveling 100 km in 2 hr. 2. Calculate the time required to move 100 m at a speed of 50 m/s. 3. What distance is covered by someone running for 2 hours if they run at 10 km/h?

7. Ex3 sp = 10 km/h d = ? d = sp  t d = 10 km/h  2 hr d = 20 km t = 2 hr GivenFormulaSetupSolution Ex1 sp = ? d = 100 km sp = ---------- sp = ---------- sp =50 ------ or km/h t = 2 hr d t 100 km km 2 hr hr Ex2 sp = 50 m/s d = 100 m t = ---------- t = --------- t = 2 s t = ? d sp 100 m 50 m/s
