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

Answer:

2.5 km

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

Step-by-step explanation:

Total distance = 24/5 km

This distance 24/5 km covered in 30 minutes.

Speed = distance * time

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

If 23/10 km covered in first fifteen minutes

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

= (48-23)/10

= 25/10 km

Now, distance = (25/10) km

Speed = 144 km/hr

Time = distance / speed

= (25/10) / 144

= (25/10*144)

= (5/2*144

= (5/288) minute
