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? Translate into expression, I will award brainiest!

21h

Step-by-step explanation:

we know that

Speed = distance / time, and as such

distance = speed * time

From the question, we are given that ...

He biked for h hrs -> b

He walked for 2 * b = 2h -> w

He ran for (1/4)(w) = 1/4 * 2h = 1/2 h -> r

The total distance traveled will then be

total distance = distance biked + distance walked + distance ran

recall that we stated that

d = s * t, now we'd apply that here

distance biked = 10 * h = 10h

distance walked = 3 * 2h = 6h

distance ran = 10 * 1/2h = 5h

total distance = 10h + 6h + 5h

Total distance = 21h
