Question

A wolf can run 110 m in 6.3 seconds. A Tiger can run 85 m in 4.2 seconds. Comparetheir unit speeds to determine which animal is faster. Round to the nearest wholeunit.Wolf speed?Tiger speed?Which one is faster?

Answer 1

Step 1. Speed of the wolf.

The wolf can run 110m in 6.3s, to calculate the unit steep, we need to make the division between the meters and the seconds:

`(110m)/(6.3s)`

The result of this division is:

`(110m)/(6.3s)=17.46\text{ m/s}`

Rounding to the nearest whole unit:

`Wolf\text{ sp}eed\longrightarrow\text{ 17m/s}`

Step 2. Steep of the tiger.

The tiger can run 85m in 4.2s, again we divide the meters and the seconds to find the unit speed:

`(85m)/(4.2s)=21.25\text{ m/s}`

Rounding to the nearest whole unit:

`\text{Tiger spe}ed\longrightarrow21\text{ m/s}`

Step 3. Which one is faster?

Since the unit speed of the tiger is larger, 21m/s vs. 17m/s, the tiger is faster.

Answer:

Wolf speed? 17m/s

Tiger speed? 21m/s

Which one is faster? Tiger
