The speed that Jo walked for the first 15 minutes is; 6 km/hr
How to Interpret Distance Time Graphs?
The distance - time graph is missing and so i have attached it.
Now, the formula for speed is;
Speed = Distance/time
The distance after 15 minutes from the graph is 1.5km.
Now, 15 minutes when converted to hours is 15/60 = ¹/₄ hr
Thus, the speed that Jo walked for the first 15 minutes is;
Speed = 1.5/(¹/₄)
Speed = 6 km/hr
