About 58 mph

Answer 2

63.09 miles per hour

Explanation:

Given: Carlos traveled 347 miles to go to his cousins’ house. It took him about 5.5 hours to drive there.

To Find: average speed in miles per hour.

Solution:

Distance traveled by Carlos to travel to his cousin's house
`=347`
`\text{miles}`

time taken by Carlos to reach his cousin's house
`=5.5`
`\text{hours}`

Now,

we know that

`\text{speed}=\frac{\text{distance}}{\text{time}}`

putting values in equation

`(347)/(5.5)`

`63.09`
`\text{miles per hour}`

Hence, average speed of carlos is
`63.09`
`\text{miles per hour}`
