Question #8016b

Answer 1

`"Average Speed" =436 "mph"`
`t = 8.03 "hr"`

Explanation:

Average Speed: `"total distance"/"total time"`

`(5668 "mi")/(13 "hr")= 436 "mph"`

At this speed, it will take:
`d = r*t`
`3500 = 436*t`
`t = 8.0275229` hours. You can convert it to minutes if you like :).

I rounded off the speed to 3 significant figures in the final answer.
