bike B is faster as it has a speed of 100 km/hr whereas bike A has speed of 96.66667 km/hr
tasneem2119:
can you show steps
how did you get 100
and 96.66667
pls explain well
pls fst
speed of bike A=145/1.5=1450/15=290/3=96.666667
speed of bike B=200/2=100 km/hr
thank you very much dear
you welcome
my pleasure

BIKE A
d1=145km
t1=1.5hrs
=1.5*60
=90min
BIKE B
d2=200km
t2=2hrs
=2*60
=120min
To find out which bike is faster we must compare their velocity
v=d/t
BIKE A
v1=145/90
v1=1.61m/s
BIKE B
v2=200/120
=1.67m/s
Since bike B has a greater velocity it means that it goes faster than bike A
hope it helps :)

just letting you know I got the velocity in m/s but if you are comfortable with km/h please get the velocity in km/h :)
hey friend, you are too right but there is no need to convert time from hours to minutes
hmm
To get velocity as meters/minute I have to. But it isn't wrong if you write it as kilometer/hour either.
