The speed of a is 17.5km/h, the speed of B is 15km / h, when the distance is 32.5km/h The speed of a and B is 17.5km/h and 15km/h respectively. When the distance between them is 32.5, what is their cycling time?
Suppose two people ride for X hours
(17.5+15)x+32.5=65
32.5x=32.5
x=1
A: the ride time is one hour
Party A and Party B ride bicycles from two places 65km apart at the same time. The speed of Party A is 17.5km per hour, and that of Party B is 15km per hour
Is the distance between Party A and Party B 32.5Km?
Hello
After (65-32.5) △ 17.5 + 15) = 32.5 △ 32.5 = 1 hour
I don't understand. I can ask
If you have any help, please remember to adopt it. Thank you
I wish you progress in your study!
