Ali cycles x km in 3 hours. If he maintains the same
RUDIKE [14]

Answer:

xy/180 km

Step-by-step explanation:

Mathematically, we have it that;

Speed = distance/ time

If he cycles x km in 3 hours

We know that ; 60 minutes = 1 hr

3 hours = 3 * 60 = 180 minutes

So the speed in km per minutes will be;

x km/180 minutes = x/180 km/minute

Recall,

Distance = speed * time

= x/180 * y = xy/180 km

Gina can type a proposal in 90 minutes. It takes 45 minutes. How long would it take to type the proposal working together?
Flura [38]

It will take 30 minutes to type the proposal when working together.

Step-by-step explanation:

Given that Gina types a proposal in 90 minutes.The other person types a proposal in 45 minutes. If working together then you can calculate as follows;

In 1 minute, Gina types 1/90 of the proposal

In 1 minute, the other person types 1/45 of the proposal

When working together, they write 1/90+1/45 =3/90 of the proposal in 1 minute

So it will take 90/3 minutes to write the proposal when working together.

90/3 minutes = 30 minutes
