From the given data, find the speed of Jack on Monday (in km/hr).

___

Open in App

Solution

Speed is generally given in km/hr e.g. 50 km/hr, which can also be represented as $\frac{50 k m}{1 h r}$

We can derive an equation for the Speed as

Speed = $\frac{D i s t a n c e}{T i m e}$

So, Jack’s speed on Monday = $\frac{2 k m}{0.5 h r}$ = 4 km/hr

Speed is generally given in km/hr e.g. 50 km/hr, which can also be represented as $\frac{50 k m}{1 h r}$

We can derive an equation for the Speed as

Speed = $\frac{D i s t a n c e}{T i m e}$

So, Jack’s speed on Monday = $\frac{2 k m}{0.5 h r}$ = 4 km/hr
