Ahummingbird can travel up to 15 meters per second.

what is the hummingbird's speed, to the nearest tenth, in miles per hour?

use 1 mile ≈≈ 1609 meters.

Speed=15 m/s
1 hour=60 minutes
60 minutes=60 minutes (60 seconds/1 minute)=3600 seconds.

 
15 m/s=(15 m/s)(1 mile / 1609 m)(3600 s/1h)=33.56... miles/hour≈
≈33.6 miles/hour.

the speed in miles per hour would be 33.6 miles/hour

Just look outside and then you’ll see where the awnser is
