Jane and sali cycled along the same 63 km route.

Alina [70]

Answer:

Sali's speed was 18.75 km/h.

Step-by-step explanation:

Jane took 3.5 hours to cycle the 63 km.

As, $Speed= \frac{Distance}{Time}$ , so the speed of Jane will be: $\frac{63}{3.5} km/h = 18 km/h$

Suppose, the speed of Sali is $x$ km/h

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

So, the time required for Jane to cycle 30 km $= \frac{30}{18}=\frac{5}{3} hours$ and the time required for Sali to cycle 30 km $=\frac{30}{x} hours$

Given that, Sali started to cycle 4 minutes or $(\frac{4}{60}) or (\frac{1}{15}) hours$ after Jane started to cycle. So, the equation will be.......

$\frac{5}{3}-\frac{30}{x}= \frac{1}{15}\\ \\ \frac{30}{x}= \frac{5}{3}-\frac{1}{15}\\ \\ \frac{30}{x}= \frac{24}{15}\\ \\ 24x=450\\ \\ x= \frac{450}{24}= 18.75$

Thus, the speed of Sali was 18.75 km/h.

Answer: 112 in sq

Step-by-step explanation: Square: 10 x 10=100 + triangle: 10 - 6 on top = 4

4 x 16 - 10 = 6 on left so... 1/2 x 6 x 4= 12 in sq. So A= 100+12= 112in sq
