Question

Vaibhav covered 24/5 km in 30 minutes. he covered 23/10 km in the first fifteen minutes. what distance did he cover in another fifteen minutes.

Answer 1

Step-by-step explanation:

In last 15 minutes he covered:

24/5-23/10=25/10=2.5 km

Answer 2

Answer: 5/288 min

Total distance = 24/5km

This distance 24/5 km covered in 30 minutes

Speed= distance *time

= (24/5)*30= 144km/ hr

If 23/10 km covered in first fifteen minutes

then rest distance =(24/5)- (23/10)

=(48 - 23)/10

= 25/10km

Now,distance =(25/10)km

speed=144km/hr

Time=distance /speed

=(25/10)×144

=(5/2*144)

=( 5/288) minutes Ans..
