If someone is going 24.85 mi/h how far will they have gone in 4 hours?

Leokris [45]

You would have to do 24.85 x 4 because the 24.85 is per hour and if someone is going for 4 hours, this is what we would have to work out. So it would equal: 99.40 miles per hour. :)

Nat2105 [25]

Answer:

The speed was $61\frac{miles}{hour}$

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

s------> the speed in miles per hour

d ----> the distance in miles

t ----> is the time in hours

we know that

$s=\frac{d}{t}$

we have

$d=305\ miles$

$t=5\ hours$

substitute

$s=\frac{305}{5}$

$s=61\frac{miles}{hour}$
