Question

How many km will a car cover in 6 hr when it is moving 50 mile/h?​

Answer 1

1 mile = 1.6 km

so 50 × 1.6 gives the answer

80 for 1 hour.

for 6 hours 480 kms

Answer 2

1 mile =1.6 km

s=?

v=1.6×50 ×1000. m

--------------------

60×60. s

=80,000

----------

3600.

=2.21m/s

t= 6h = 21,600s

u=0

find a by v=u+at

then

s by s=ut+1/2at^2
