Answer:
<em>Sali's speed was 18.75 km/h.</em>
Step-by-step explanation:
Jane took 3.5 hours to cycle the 63 km.
As, 
, so the speed of Jane will be: 
Suppose, the speed of Sali is 
km/h
Sali caught up with Jane when they had both cycled 30 km.
So, <u>the time required for Jane to cycle 30 km</u> 
and <u>the time required for Sali to cycle 30 km</u> 
Given that, Sali started to cycle 4 minutes or 
after Jane started to cycle. So, the equation will be.......
Thus, the speed of Sali was 18.75 km/h.
I think it would be 5/7 because it says that square B is 5/7 of square A.

Answer:
40t⁶
Step-by-step explanation:
Since -4t⁵ and -10t have the same variable (base), we can multiply their coefficients (numbers) and add their exponents
-4t⁵ * -10t = 40t⁶
Since both numbers are negative, when we multiply them, they cancel out.
SInce both variables are the same (both are t), we can just add their exponents together. Even though we don't see an exponent above -10t, we can assume that it is 1. Think of it as this, -10t = -10t¹ because it just represents -10t, -10t (specifically the t) isn't being multiplied by anything.
