Question

. Joaquin played basketball with his friends from 1:10 to 3:35. He arrived home 20 minutes later. How many minutes passed from the time Joaquin started playing basketball until the time he arrived at home?​

Answer 1

165 minutes

Explanation:

To solve for the number of minutes that Joaquin played for, we can use this expression:

(let 'a' represent how much time passed from the time Joaquin started playing basketball until the time he arrived at home)

• 1:10 + a = 3:35

Subtracting 1:10 from each side:

• 1:10 - 1:10 + a = 3:35 - 1:10

1:10 - 1:10 cancels out to 0, while 3:35 - 1:10 is equal to 2:25.

So, the expression is now:

• a = 2:25

So, 2 hours and 25 minutes passed.

If we know that 1 hour is equivalent to 60 minutes, we can use this expression to solve for however many minutes are in 2 hours:

• 2 × 60 = 120

Now we need to add on the number of minutes and the time it took him to get home:

• 120 + 25 + 20 = 165

Therefore, 165 minutes passed from the time Joaquin started playing basketball until the time he arrived at home.
