Answer 1

Answer:

Step-by-step explanation:

Given value

Distance =750m

Speed=24km/h =>24×1000=24000m

Time=distance /speed

Time =750/24000

=1/32

=0.03125h

Answer 2

Answer:

1 min 48 sec

Step-by-step explanation:

Speed= 24km/hr                   Distance= 720m

= 24 x 5/18 m/s

= 20/3 m/s

Therefore, Time= Distance/Speed= 720/20/3

= 720 x 3/20

= 108 sec
