Question

What’s the average speed in km/h of a boat that moves 15 km across a lake in 45 min?

Answer 1

20 km/hr

Explanation:

Hey

Distance= 15km

Time= 45min

Since the unit for time is hours, we will convert 45 minutes to hours

45/60 = 0.75 hours

Speed= d/t

= 15/0.75

= 1500/75

= 20 km/h

Hope this helps
