Question

It took a sled dog team 8.5 hours to travel 161.5 kilometers. What was the average speed of the sled dog team in kilometers per hour?

Answer 1

`19 "km"/h`

Explanation:

This is a ratio, also called a quotient, and it is a division problem. To obtain the units desired of km/h you simply divided the given value of kilometers by the hours traveled:

`161.5/8.5 = 19`

Answer 2

`"19 km/hr"`

Explanation:

`"speed" = "distance traveled" /"time taken"`

• `"distance = 161.5 km"`
• `"time taken = 8.5 hrs"`

So

`"speed" = "161.5 km"/"8.5 hr" = "19 km/hr"`
