Geral and michelle went on a 24 bike-ride. By lunch time they had ridden 5 eigth of the total distance. How many miles did they have left to ride after lunch?

5/8 * 24 = 15 miles

24 - 15 = ?

45 To answer this question, we first need to find out how far Geral and Michelle had ridden before lunch.

Given that they had ridden 5 eighths of the total distance, we can calculate the distance they covered before lunch by multiplying the total distance by 5/8.

Let's assume the total distance they rode is represented by the variable "d", and the distance covered before lunch can be represented by the variable "x".

Mathematically, we can write this as:

x = (5/8) * d

Now, since the total bike ride was 24 miles, we can substitute "d" with 24:

x = (5/8) * 24

To simplify this expression, we can divide both 5 and 24 by 8 to get a decimal.

x = (5/8) * 24
x = (5 * 3) / (8 * 1)
x = 15 / 8
x = 1.875

Therefore, Geral and Michelle had ridden approximately 1.875 miles before lunch.

To find out how many miles they had left to ride after lunch, we can subtract the distance covered before lunch from the total distance:

Distance left = Total distance - Distance covered before lunch
Distance left = 24 - 1.875
Distance left = 22.125

Therefore, Geral and Michelle had approximately 22.125 miles left to ride after lunch.
