A taxi hurries for 1 hour 54min with a constant speed of 93km and then for another 5 hours 15min with a constant speed of 72km.
Ghella [55]

Speed  = 93km /h  and  72km/h

Answer: The taxi went a distance of 554.7km

Step-by-step explanation:

Speed  = Distance / Time

Distance covered in the first trip = Speed x Time

Time = 1 hour 54 min =1+0.9 hours  =1.9hours

=93km / h x 1.9 hours =176.7km

Distance covered in the second  trip = Speed x Time

Time = 5 hours 15min = 5+0.25hours  =5.25hours

=72km / h x 5.25hours =378 km

Total distance =176.7km+378 km

=554.7km

Explain or show how you could find 5 ÷ 1/3 by using the value of 5x3.​
erastova [34]

Answer:

20

You could find 5/⅓

by using 5 × 3

Knowing that:

Any number multiplied by 1, gives the number itself.

Dividing any number by itself gives 1.

Writing 5/⅓ as 5/⅓ × 1 doesn't change the value.

Then I can write 5/⅓ as

5/⅓ × (5×3)/(5×3) = 1

This can become

[5×(5×3)] / [(⅓) × (5×3)]

= 75/(15/3)

= 75/5

= 15

or

12/ 3/5

= [12/ (3/5)] × [(5×3)/(5×3)]

= 12×(5×3) / (3/5)×(5×3)

= (12×5×3) / [(3×5×3)/5]

= 180 / (45/5)

= 180 / 9

= 20

Answer:

  B.  (-5/13, 12/13)

Step-by-step explanation:

The point at distance x from π in the clockwise direction is the reflection of point T across the y-axis. Hence the coordinates are the same, except that the sign of the x-coordinate is reversed.

The point of interest is (-5/13, 12/13).
