Question from jacob, a student: If it took an ostrich 2.5 seconds to travel 110 feet and the average speed is 44 feet/ seconds, what was the ostrich's speed in miles per hour? |
Hi Jacob,
A cheetah can run as fast as 110 ft/sec. If I want that in miles per hour then the units tell me what to do
There are 5280 feet in a mile and 60 × 60 = 3600 seconds in an hour so lets fill in the numbers
Now try the ostrich speed.
