Question

Train A travels 1500km in 12 days and train B travels 1800km in 9 days. Find the ratio of their speeds.​

Answer 1

Answer:

Speed = distance /time

Train A:-

Time = 12 days

Distance = 1500 km

Speed = 1500/12 = 125 km/day

Train B :-

Time = 9 days

Distance = 1800 km

Speed = 1800/9 = 200 km/day

Note :- Since we have to take the ratio of the speed we don't convert days into hours because the units will cancel each other

Ratio of speed = 125/200 = 25/40 = 5/8

Ratio = 5 : 8

happy 2 help :)

Step-by-step explanation:

Answer 2

Answer:

since speed= D/T

A/B=(1500/12)/(1800/9)

=125/200

=25/40

=5/8
