A car drives 494 km in 4 hours 45 minutes what is its average speed in kilometers per hour?

The average speed is 104 kilometer per hour

Solution:

Given that,

A car drives 494 km in 4 hours 45 minutes

To find: Average speed in kilometers per hour

The average speed is given by formula:

From given,

Distance = 494 km

Time = 4 hours 45 minutes

We know that,

1 hour = 60 minutes

Therefore,

Thus,

time = 4 hours 45 minutes = 4 hour + 0.75 hour = 4.75 hour

Thus average speed is:

Thus average speed is 104 kilometer per hour

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
