Andy cycles a distance of 30 km at an average speed of 24 km/h. He then runs a distance of 12 km at an average speed of 8 km/h.
Work out the total time Andy takes. Give your answer in hours and minutes.
Answer:
1 Hour and 20 minutes
Step-by-step explanation:
Time = Distance ÷ Speed
The total time taken by Andy is (1.25 + 1.5) 2.75 hrs or 165 minutes and this can be determined by using the formula of speed.
Given :
Andy cycles a distance of 30 km at an average speed of 24 km/h. He then runs a distance of 12 km at an average speed of 8 km/h.The formula of speed is used to determine the time taken by Andy to cover the total distance. The formula of speed is given by:
[tex]\rm s = \dfrac{D}{t}[/tex]
where 's' is the speed, 'D' is the distance and 't' is the time.
Now, the time taken by Andy to cover the distance of 30 Km with the speed of 24 Km/hr is:
[tex]\rm 24 = \dfrac{30}{t}[/tex]
[tex]t = \dfrac{30}{24}[/tex]
t = 1.25 hrs.
Now, the time taken by Andy to cover the distance of 12 Km with the speed of 8 Km/hr is:
[tex]\rm 8 = \dfrac{12}{t}[/tex]
[tex]t = \dfrac{12}{8}[/tex]
t = 1.5 hours.
So, the total time taken by Andy is (1.25 + 1.5) 2.75 hrs or 165 minutes.

3(6x+8)=24+18x what the answer
Answer:
0=0 or as known as infinite solution
Step-by-step explanation:
when answering a type of question there are 3 steps
1) Distribute: 3(6x+8)=24+18x
3 x 6x= 18x 3 x 8= 24
18x +24 = 24 + 18x
2) Subtract 24 from both sides of the equation:
18x + 24 = 24 + 18x
-24 -24
18x + 0 = 0 + 18x
3) Subtract 18x from both sides to set apart (x) : 18x = 18x
-18x -18x = 0 = 0
