Question

plzz answer fast sum no. 6

Answer 1

6):-
(I):-

Distance=600 m,

time=5 min=5×60 sec=300sec,

therefore

speed=distance/time,

speed=600/300=2 m/sec,

speed=2×18/5 km/hr=7.2 km/hr,

(II):-

now Distance travelled in 3/2 hours= 7.2×3/2,

=10.8 km,


(III):-

time taken by the cyclist to cover 1.8 km = distance/speed,


=1.8/7.2,

= 1/4 hours,

=1/4×60 min,

=15 min
