Question

.Amit cycles to his school at an average speed of 14 km/hour. It takes him 30 minutes
to reach the school in time. At what speed should he cycle, if he wants to reach
two minutes earlier?​

Answer 1

Speed =14 km/hr

Time =30 minutes

We know,

Speed=

time

distance

Distance of school =

60

14×30

=7 km

New time in which 7 km is to be covered

=30−2=28 minutes =

15

7

hours

Speed=

time

distance

=

7

7×15

=15 km/hr

Answer 2

Answer:

Speed =14 km/hr

Time =30 minutes  

Speed=  distance  / time

Distance of school =14 * 30 /  60  = 7 km

New  time in which 7 km is to be covered  = 30 − 2 = 28 minutes =  7 / 15 hr

​Speed=  distance  / time  

          = 7 * 15  / 7 km/hr

          =15 km/hr

HOPE THIS HELPS YOU! :)
