Charles is going camping with his family their campsite is 5/8 mile away they walk a steady speed of 1 7/8 miles per hour how many minutes will it take them to get to the campsite?

time=distance/speed=(5/8)/(15/8)=1/3 hour or 20 min

To find out how many minutes it will take Charles and his family to get to the campsite, we need to convert the given speed from miles per hour to miles per minute. Here's how:

1 hour = 60 minutes

Now let's convert 1 7/8 miles per hour to miles per minute:

1 7/8 miles per hour can be written as the improper fraction (15/8) miles per hour.

To convert it to miles per minute, we need to divide by 60 to account for the conversion from hours to minutes:

(15/8) miles per hour ÷ 60 minutes = 15/8 ÷ 60 miles per minute

Now let's simplify the fraction:

15/8 ÷ 60 = 15/8 ÷ 60/1 = 15/8 × 1/60 = 15/480

Simplifying the fraction further, we get:

15/480 = 1/32

So, the speed of Charles and his family is 1/32 miles per minute.

Next, we need to calculate the time it will take them to travel the distance of 5/8 mile:

Time = Distance / Speed

Time = (5/8) mile / (1/32) miles per minute

To divide by a fraction, we can take the reciprocal and multiply:

Time = (5/8) mile × (32/1) minutes per mile

Now, let's calculate the time:

Time = (5 × 32) / (8 × 1) = 160/8 = 20 minutes

Therefore, it will take Charles and his family 20 minutes to get to the campsite.
