Question

HELP!!! How far have I travelled if I biked at 10mph for hhrs, I walked at 3mph for twice as long as I biked, and ran at 10mph for one quarter as long as I walked?

Answer 1

21h miles

Step-by-step explanation:

The appropriate relation is ...

distance = speed · time

__

We are given that ...

biking time = h

walking time = 2h

running time = (1/4)(2h) = h/2

The total distance traveled is ...

total distance = biking distance + walking distance + running distance

= (10)(h) +(3)(2h) +(10)(h/2)

= 10h + 6h + 5h

total distance = 21h . . . miles:

Answer 2

21h miles

Explanation:

The appropriate relation is ...

distance = speed · time

__

We are given that ...

biking time = h

walking time = 2h

running time = (1/4)(2h) = h/2

The total distance traveled is ...

total distance = biking distance + walking distance + running distance

= (10)(h) +(3)(2h) +(10)(h/2)

= 10h + 6h + 5h

total distance = 21h . . . miles
