grandymaker [24]

Answer:

t = 6 s

Step-by-step explanation:

Given that,

Sherry is driving 390 miles to visit The gateway arch in St. Louis.

She drives at an average rate of 65 miles per hour.

We need to find the amount of time it will take Sherry to get to the arch. Let the time is t.

Speed = distance/time

$t=\dfrac{d}{v}\\\\t=\dfrac{390}{65}\\\\t=6\ h$

Hence, it will take 6 hours to get to the arch.
