10. Every car in the USA is fitted with a mileometer. The mileometer shows the total distance that a car has travelled.

Evan is a salesman.

This is the reading on his mileometer at the start of one week. 1 2 5 4 6 5 miles

This is the reading on his mileometer at the end of the week. 1 2 6 3 3 5 miles

a) How many kilometres has Evan travelled in this week?

b) Evan is paid 20 cents for each kilometre he travels. This is to pay for the petrol he uses.

Work out the amount Evan is paid this week for the petrol he uses. Give your answer to the nearest dollar.

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
