Frank and mary are traveling to the beach which is 520 mi from their home if they travel at an average speed of 65 miles per hour and they don't make any stops how long will it take them to get there

It will take 8 hours for Frank and Mary to get to the beach

Step-by-step explanation:

Step 1: Give expression for calculating

d=s×t

where;

d=distance traveled i miles

s=speed in miles per hour

t=time in hours

in our case;

d=520 miles

s=65 miles per hour

t=unknown

Step 2: Solve for the unknown, t

In order to solve for t, the expressions can be rearranged as follows ;

t=d/s

replacing values for d and s;

t=520/65

t=8 hours

It will take 8 hours for Frank and Mary to get to the beach
