Question

HELP ME PLEASE

Hank the hiker would like to go on a hike. He only has four hours available today for the hike. The expression

1/2d + 1/2e
is used as a general guide to determine how much time, in hours, a hiker should allow for hiking a trail with a distance of d miles and an elevation gain of e thousand feet. The trail Hank would like to hike is 6 miles long and has an elevation gain of 3000 ft. Will Hank be able to complete this hike in the block of time he has available today?

Answer 1

No.

Explanation:

Amount of time that Hank has today for hike = 4 hours

Lengtht of hike trail = 6 miles

Elevation gain of trail = 3000 feet

The expression Hanks use as a general guide is:

`(1)/(2)d+(1)/(2)e`

Here,

d is the distance in miles, so for given case d = 6

e is the elevation gain in thousands, so for given case e = 3

Using these values, the approximate time Hank would need for the hike comes out to be:

`(1)/(2)(6)+(1)/(2)(3)= 4.5`

Thus, Hank would need 4.5 hours to complete the hike. Since, he has only 4 hours available today he wont be able to complete the hike.
