How far can a cyclist travel in 1.5 hours if his average speed is 12 km/hr?

Mathematics
1 answer:
Lesechka [4]3 years ago
5 0

Answer:

A cyclist can travel 18 kilometres in 1.5 hours.

Step-by-step explanation:

The ratio for the cyclist's speed is 12 km/1 hr. If I were to find the ratio for kilometres per 1.5 hour, I would need to multiply the denominator of 1 (aka 1 hour) by 1.5 to get (1.5 hours). Whatever you do to the bottom, you have to do to the top. So I multiply the numerator of 12 (12 km) by 1.5 to get 18 km.

12 km/1 hr → 18 km/1.5 hrs

The distance between two points is 6_/6.One endpoint is (4,-1). It is known that the y-coordinate of the other endpoint is 9.
babunello [35]

The x-coordinate of the given endpoint will be "x = 4 \pm 2\sqrt{29}".

According to the question,

The end points are:

  • (x_1,y_1) = (4,-1)
  • (x_2, y_2) = (x,9)

Distance,

  • 6\sqrt{6}

As we know,

The distance formula,

→ Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

By substituting the values, we get

→         6\sqrt{6} = \sqrt{(x-4)^2+(9+1)^2}

→          216= (x-4)^2+100

→   (x-4)^2 = 116

→       x-4 = \pm \sqrt{116}

→       x-4=\pm 2\sqrt{29}

→             x = 4 \pm 2\sqrt{29}                

Thus the above answer is right.

pav-90 [236]

Answer:

£6655

Step-by-step explanation:

Given data

Principal=  £5000

Rate= 10%

Time = 3 years

FInal Amount A=???

The expression for the compound interest is given as

A=P(1+r)^t

substitute

A=5000(1+0.1)^3

A=5000(1.1)^3

A=5000*1.331

A= £6655

Hence the final Amount is  £6655
