The speed of Sali is 18.75 km/hr.

Given,

Total distance travelled by Jane and Sali =63 km.

The total time is taken by Jane=3.5 hours.

Sali started to cycle 4 minutes after Jane started to cycle $=\frac{4}{60}=\frac{1}{15}$ hours.

<h3>What is the formula to find speed?</h3>

The formula to find speed is $Speed=\frac{Distance}{Time} \ km/hr$ .

The speed of Jane $=\frac{63}{3.5}=18 \ km/hr$ .

Let the speed of Sali be $x \ km/hr$ .

Sali caught up with Jane when they had both cycled 30 km.

Thus, $\frac{30}{18}-\frac{30}{x}=\frac{1}{15}$

$\implies \ \frac{30x-540}{18x} =\frac{1}{15}$

$\implies \ 15(30x-540)=18x$

$\implies \ 5(30x-540)=6x$

$\implies \ 150x-2700=6x$

$\implies \ 144x=2700\implies \ x=18.75$

Therefore, the speed of Sali is 18.75 km/hr.

Solve the equation. Start Fraction y minus 5 over 3 End Fraction= 1 A. –2 B. 8 C. 18 D. 6

EastWind [94]

Answer:

B. 8

Step-by-step explanation:

Start Fraction y minus 5 over 3 End Fraction= 1

This statement above is written Mathematically as:

y - 5/3 = 1

We solve the Equation below

Step 1

y - 5/3 = 1

We cross Multiply

y - 5 = 3 × 1

y - 5 = 3

Step 2

Add 5 to both sides

y - 5 = 3

y - 5 + 5 = 3 + 5

y = 8

Option b is the correct answer
