50m/min

Answer 2

Answer:

a) 50 m/s

b) 180 km/h

Step-by-step explanation:

a) distance cover by student from home to school

= 1500 m

time taken by student = 30 minutes

we have,

speed = distance/time

= 1500/30

= 50 m/s

b) distance cover by student from home to school

= 1500 m

= 1500/1000 km

= 1.5 km

time taken by student = 30 minutes

= 30/3600 h

= 1/120 h

we have,

speed = distance/time

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{1.5}{ \frac{1}{120} }$

= 1.5 × 120

= 180 km/h
