Question

A bicycle travels in a straight line at a distance of 12km / h for 45. How far does it travel?

Answer 1

9 km

Step-by-step explanation:

I guess you mean 45 minutes.

1 hour = 60 minutes

45 minutes = 45/60 = 0.75 hours

Proportions:

12 km ⇔ 1 hour

B km ⇔ 0.75 hours

B = 12*0.75/1

B = 9 km
