Question

Raju cycles to school at a speed of 16 km/h
and reaches the school in 30 minutes. Today
he started late by 10 min. At what speed
should he cycle to reach school on time?​

Answer 1

Answer:

6.66 m/s or 24 km/hr/

Step-by-step explanation:

1st turn 16km/h into m/s.

speed=4.44m/s

time taken = 30 mins = 1800 sec

distance = speed * time = 7992 m

  then,

since he is 10 minutes late time taken = 30 min - 10 min = 20 mins = 1200 sec

we know distance=7992m

speed = distance/ time =7992/1200 = 6.66m/s = 24 km/h

hope it helped
