A car covers 200km in $4\frac{1}{2} $h and then another 240 km in $3 \frac{1}{2}$ h. Find its average speed.

Given:  A car covers 200km in  $4\frac{1}{2} $h and then another 240 km in  $3 \frac{1}{2}$ h

To find: The average speed

Solution

Total distance travelled = 200 + 240 = 440 km

     Total time taken =$4\frac{1}{2} $ +$3 \frac{1}{2}$= 8 hours

    Average speed = $\frac{Total \ distance \ travelled}{Total \ time \ taken}$

                                = $\frac{440}{8}$ = 55 kmph 

      So Average speed = 55 kmph
