Question

Jacobo tan 10 miles in 80 mins at that rate how far would he run in 2.5 hours

Answer 1

Answer:

He covered 10 miles in 80 minutes,

Therefore by formula of speed,

Speed= distance/time

S1=10/80—————–(1)

At the same rate i.e at same speed[ S1 = S2],

S2 = X/150—————(2)———-(2.5 hours = 150 minutes)

Therefore from (1)&(2),

10/80=X/150

1500 = 80X

Therefore,

X= 1500/80

X= 18.75

Ans: Jacob ran 18.75 miles in 2.5 hours.

Answer 2

Step-by-step explanation:

Jacob ran 10 miles in 1.3 hours (80 minutes)

d = rt

d - distance covered

r - rate of speed or velocity

t - time

So the rate of speed or velocity is

r = d/t

=> r = 10/1.3

=> r = 7.69230769 miles per hour

Now the distance covered by Jacob with the same speed or velocity in 2.5 hours ( 150 minutes) is

d = rt

=> d = 7.69230769 × 2.5

=> d = 19.2307692 miles

Hence,Jacob must have covered 19.2307692 miles (approx.) in 2.5 hours.
