GuDViN [60]

Answer:

The balance in her lunch account at the end of the day on Friday is -$1.15.

Step-by-step explanation:

The balance at the end of the week will be the result of adding up the initial balance with the amount deposited on Monday minus the total amount spent that week.

Balance=$22.60-$23.75

A van and a truck both drove from Town A to Town B. The distance
Gala2k [10]
First we need to find out the time it took for the truck to reach town B.

Speed= \frac{Distance}{Time}

40= \frac{200}{T}
T=5hours

Now, because the van left 1.5 hours earlier and reached the destination 2.5 hours before, it took 1 hour less the the truck to arrive.

5hours-1hour=4hours which is the time it took for the van to arrive.

Now we use the speed equation again to work out speed.

Speed= \frac{200}{4}

Speed=50mph = speed of van

Hope this helped :)
