Question

Distance of 10^8 in 30min .find speed in km/h

Answer 1

Answer:2,00,000 km/h

Step-by-step explanation:

If distance is in metres then 10^8m = 10,00,00,000 m =1,00,000 km.

30 minutes =1/2 hour =

Therefore, speed = distance/time

=1,00,000/1/2

=1,00,000*2

=2,00,000 km/h

Answer 2

Step-by-step explanation:

Distance = Speed × time

given : dist. = 10^8=

100000000

time = t = 30 min.

= 1/2 hr.

distance = speed× time

100000000 = a × 1/2

a = 100000000 × 2

= 200000000

Speed = 200000000 km/ hr.
