Question

Suppose to travel 162 miles in 3 hours .use the formula d=st to find the average speed

Answer 1

Reduce:

162 miles

--------------- = 54 mph

3 hrs

If we start with distance = rate times time, we can solve for rate:

rate = distance / time. That's what I've just done (above).

Answer 2

Distance = Speed x time = 162 x 3 = 486 miles/hour

Answer: 486 miles/hour
