Question

A school bus takes45 minutes to cover a distance of 18 km. Calculate its speed in km /h and m/sec

Answer 1

#Here Distance = 18 km Time taken = 45 min = 45/60hrSpeed = 18 ×60÷45 = 24km/hr I hope it helps  

Answer 2

Answer:

45 minutes = 45 / 60 h = 3/ 4 h . Distance covered = 18 km  .Time taken = 3/4h

- > speed = ( 18 of 3 / 4 ) km / h = ( 18 x 4 / 3 ) km / h = 24 km / h .

LET US EXPRESS THE SPEED IN M / S .

- > Distance = 18 x 1000 m  . Time = 45 x 60 s .

- > Speed = 18 x 1000 m / 45 x 60 s = 6 . 67 m / s .
