Raghu cycles to his school at an average speed of 12 km/hr. It takes him 20 minutes to reach
the school. If he wants to reach the school in 15 minutes what should be his average speed?
Please give me a verified answer. ​

Answer 1

Answer:

Raghu's speed will be 16 km/hr

Step-by-step explanation:

S=12 km/hr

D=20min

so, D=S*T

D=12*20

D=240 m

Raghu wants to cover 240m in 15 min,so he need to cover it with a speed of,

S=D/T

S=240/15

S=16km/hr

Hence,Raghu's speed will be 15km/hr to reach his school in 15min.
