Question

The speed of trains Q and W are in the ratio 7 : 8. What is the speed of the train Q, if train W runs 480

kms 5 hours?​

Answer 1

The speed of train Q is 84 kmph

Answer 2

Answer:

84km/h

Step-by-step explanation:

you know train W runs 480 km 5 hours,so then you need to know how many kms can it run 1 hours. So we use 480/5 , then we know train W's speed is 96km/h.

The ratio of it and train Q is 7:8, so we use 96 devided by 7, that's 12. Then use 12 times 7 which is 84km/h. That's the speed of train Q.
