Question

pls help I am too (dum) too answer​

Answer 1

Answer:

Let

X - be hilda speed

X+10 - be enrico speed

S - distance covered by Enrico

43.5-S - distance covered by Hilda

Conversion:

45 mins x 1hr/60 mins = 0.75 hour

Distance = Speed x Time

Then,

S = (x+10)(0.75) ---> Equation 1

S= 0.75x + 7.5

43.5-S = x(0.75) ---> Equation 2

43.5-S = 0.75x

Eq. 1+Eq. 2

43.5=1.5x+7.5

1.5x=43.5-7.5

1.5x=36

x=24

Then,

Hilda speed is 24kph, Enrico speed is 34 kph

Step-by-step explanation:

Answer 2

Answer:

Enrico: 24 K/h & Hilda: 34 K/h

Step-by-step explanation:

1) $v_{1} = v_{2} - 10 (K/h).$

2) $v_{1} + v_{2} = v_{1} + v_{1} + 10 = 2v_{1}.$

3) $2v_{1} = S/t = \frac{43.5}{\frac{3}{4}} = 58$

4) $v_{1} + v_{1} + 10 = 58$

5) $2v_{1} = 48$

6) $v_{1} = 24 (K/h)$

7) $v_{2} = 24 + 10 = 34 (K/h)$
