Answer:
is 200 times larger than 
Step-by-step explanation:

To compare both values we divide the exponents

6 divide by 3 is 2
for simplify exponents we use exponential property
a^m / a^n = a^(m-n)


is 200 times larger than 
Answer:
-0.125x + 12.5
Step-by-step explanation:
10.5 hours
let t be time then distance travelled by both is
Mr Burges ⇔ d = 50t ( distance = speed × time )
Mrs Burges ⇒ d = 70(t - 3)
At the point of overtaking both will have travelled the same distance
equating their distance and solving for t
70(t - 3) = 50t
70t - 210 = 50t ( subtract 50t from both sides )
20t - 210 = 0 ( add 210 to both sides )
20t = 210 ( divide both sides by 20 )
t = 10.5 hours
