Two mechanics worked on a car. the first mechanic worked for 5 hours, and the second mechanic worked for 15 hours. together they
Ksenya-84 [330]

Alright, lets get started.

Suppose first mechanic charges= x

So, second mechanic charges will be = (125 - x) (because total of their rates was 125)

first mechanic worked for 5 hours, and the second mechanic worked for 15 hours and together they charged a total of $1225

Means

5 x + 15 (125-x) = 1225

5 x + 1875 - 15 x  = 1225

1875 - 10 x = 1225

Adding 10 x in both sides

1875 - 10 x + 10 x = 1225 + 10 x \\1875 = 1225 + 10 x

Subtracting 1225 from both sides

1875 - 1225 = 1225  + 10 x - 1225\\650 = 10 x

Dividing 10 in both sides

\frac{650}{10}  =  \frac{10x}{10}

x = 65

For second mecahnics rate = 125 - 65 = 60

Hence The mechanic who worked 5 hours charged $ 65 per hour, the one who worked 15 hours charged $ 60 per hour: Answer

Hope it will help :)

as the earth revolves around the sun it travels at a speed of 18 miles per second. covert this speed to miles per minute at this
morpeh [17]
If we have the speed of 18 miles per second, 18miles/s
to find out what is the speed in 1 minute we will need to multiply 18 by 60, as there are 60 seconds in 1 minute
18 miles..............................1 second
?miles..................................60 seconds(1min)
18*60=1080 miles
we have 1080 miles/minute
in 2 minutes we have 1080*2=2160 miles
hope it helps
