Final answer:

Martina can walk 3.75 miles in one hour at her current pace, calculated by multiplying her walking speed of 3/4 mile per 1/5 hour by 1 hour.

Step-by-step explanation:

The question is about determining how far Martina can walk in one hour based on her rate of walking 3/4 of a mile in 1/5 of an hour. To find the distance Martina can walk in one hour, which is simply finding her walking speed, we set up a ratio where the distance is in the numerator and time is in the denominator.

The ratio for Martina's walking speed is:

Speed = (Distance)/(Time) = (3/4 mile)/(1/5 hour)

To find out how far Martina can walk in one hour, we will multiply this speed by 1 hour:

Distance in one hour = Speed × 1 hour

This calculation simplifies to:

Distance in one hour = (3/4 mile)/(1/5 hour) × 1 hour

Distance in one hour = (3/4 × 5/1) mile

Distance in one hour = 15/4 mile or 3.75 miles

Therefore, Martina can walk 3.75 miles in one hour at her current pace.

Hey there!


To make this easier, we need to transform the numbers in decimal

3/4 = 0.75

1/5 = 0.2

So Martina walks 0.75 miles in 0.2 hour. They want us to find how far will she wake in 1 hour.

So we say:

0.75......>0.2 hr
x...........1 hr

Cross multiply

0.2 * x = 1 * 0.75

0.2x = 0.75

x = 0.75/0.2

x = 3.75

Martina will work 3.75 miles in one hour.

I hope this helps!
