Question

A man travels 27km in total 4 hours. He travels first 15km at a average speed of

6km/hr. Find his speed in the remaining distance​

Answer 1

Answer:

8km/h

Step-by-step explanation:

Total time= 4hrs

First 15km at speed of 6km/hr

then, time required for first 15 km is = 15/6

time for first 15 km= 2.5hrs

Then, total distance- 15 km= 12 km

And time required for 12 km =

Total time- time required for first 15km

= 4hrs -2.5hrs

= 1.5 hrs

Speed for another 12 km = Distance/ Time

= 12/1.5

= 8km/hrs.
