Gopal spent 3/5 of his money in the first week and 1/3 of the remainder in the second week. He spent $110 altogether. How much m
saul85 [17]
First let's find out what 1/3 of 3/5 is. To do that, we have to multiply 1/3 by 3/5 which equals 3/15, which simplifies to 1/5. 

Since we know that Gopal spent 110, we know that 110 is equal to 4/5. We have to find the last 1/5. To do this, divide 110/5 = 22

The answer is 22 :)

I hope this helps! :)

Elena-2011 [213]

Answer:

74.6018 Miles per hour

Step-by-step explanation:

Step 1: How many seconds are in an hour? There are 60 seconds in a minute and 60 minutes in an hour, so there are 60*60 = 3600 seconds in an hour.

Step 2: How many feet are in a mile? There are 5280 feet in a mile.

Step 3: To convert feet per second to miles per hour, first multiply by 3600, then divide by 5280. The fraction 3600/5280 reduces to 15/22.

To convert feet per second to miles per hour, multiply by 15/22.

So: 109.416 feet/second * (15/22) = 74.6018 miles/hour
