Two cars are travelling towards each other with a speed of 45 km per hour and 63 km per hour respectively what is the distance in kilometre between the two cars 10 second before they collide

Question

Answer 1

0.3 kms.
solution: (63+45)*10/(60*60)

Answer 2

0.3 kms.
solution: (63+45)*10/(60*60)

Answer 3

km/h convert into m/s, then find the answer,
45*5/18=12.5
63*5/18=17.5
add both speed = 30m/s
then convert into 10 second
so 30*10= 300 m.

Answer 4

km/h convert into m/s, then find the answer,
45*5/18=12.5
63*5/18=17.5
add both speed = 30m/s
then convert into 10 second
so 30*10= 300 m.
